VI: Konfidenzintervalle - die Alternative zum p-Wert

2003

Confidence intervals combine the ideas of clinical relevance and statistical significance by using one instructive expression, which enables remarkable reduction of table structures and result sections in scientific publications. Confidence interval based conclusions can be transferred from a clinical trial to its underlying study population with respect to a residual statistical error probability, i.e. the significance concept is retained. However, their presentation using the original unit of the clinical endpoint under consideration allows for immediate interpretation of the results' clinical impact. For example, the comparison of two therapy groups based on a binary endpoint becomes fea…

Systematic review and meta-analysis found that malnutrition was associated with poor cognitive development

2021

Aim: Malnutrition is a major public health issue that has been associated with high susceptibility for impaired brain development and mental functioning. However, to date studies on this topic have not been collated and appraised. This systematic review and meta-analysis investigated the association between malnutrition and cognitive development. Methods: We searched the MEDLINE, Scopus, CINAHL, Embase PsycINFO and Cochrane Library databases in English up to 8 December 2020. All studies reporting an association between nutritional status and cognitive development were included. p values of less than 0.05 were considered statistically significant and the results are reported as standardised …

Muscle strength before and mortality after a bone fracture in older people

2002

We studied whether muscle strength measured before a bone fracture predicts mortality following the fracture. The participants were a sub-cohort of 82 people of a total of 493 Evergreen project participants initially aged 75- and 80 years, who had participated in knee extension strength tests as part of the baseline examinations, and who subsequently suffered at least one bone fracture. Maximal isometric knee extension strength was measured at baseline using an adjustable dynamometer chair. Fracture surveillance was carried out from patient records for 5 years, and mortality surveillance from population register for 10 years after baseline examinations. Average time till a fracture occurred…

Late Breaking Abstract - Predictive value of FeNO in patients with non-specific respiratory symptoms: a randomised controlled trial

2017

Background: Fractional exhaled nitric oxide (FeNO) can predict treatment response in asthma, but little is known of its utility in patients with non-specific respiratory symptoms (NSRS). Aims and objectives: To evaluate the association between baseline FeNO and response to treatment with inhaled corticosteroids (ICS) in patients with NSRS. Methods: This was a multi-centre randomised, placebo-controlled trial, carried out in UK and Singapore. It consisted of a 2-week assessment period to establish baseline measurements and a 4-week treatment period with either extrafine ICS (200 µ beclomethasone bid) or placebo. NIOX VERO (Circassia) was used to measure baseline FeNO. The primary endpoint wa…

Effect of storage time and donor sex of transfused red blood cells on 1-year survival in patients undergoing cardiac surgery: an observational study

2016

BACKGROUND Red blood cell (RBC) storage lesions and RBCs from females transfused into male recipients may have adverse effects on transfusion recipients' survival. We hypothesized that the effect of donor sex and the effect of age of blood on mortality would be most apparent in cardiac surgery patients. STUDY DESIGN AND METHODS Using data from French Blood Services and two university hospitals, we conducted a retrospective cohort study on cardiac surgery patients whose first transfusion occurred between 2007 and 2011. The age of blood and donor sex effects on 1-year survival were studied using Cox regression modeling, with time-dependent stratification on the number of RBCs and adjustments …

Serum Heat Shock Protein 60 in Acute Heart Failure: A New Biomarker?

2012

Heat shock protein 60 (HSP60) is a mitochondrial protein constitutively expressed in the majority of cells, and its expression is up-regulated by a variety of stressors. In heart failure, HSP60 is released from cardiomyocytes. The authors speculate that increased serum HSP60 (sHSP60) may be related to the severity of heart failure. This investigation sought to assess the association between sHSP60 and the composite end point of death ⁄ readmission in patients with acute heart failure (AHF). A total of 132 consecutive patients were admitted for AHF. The independent association between sHSP60 and the end point was assessed with Cox regression. During a median follow-up of 7 months (interquart…

Behaviour-change interventions in primary care: Influence on nutrition and on the metabolic syndrome definers

2011

The purpose of this paper was to examine whether interventions influenced patients' (i) consumption of fish; whole grain products; fruits and vegetables; (ii) overall nutrition, that is, the three former as an index; and (iii) clinical outcomes in terms of metabolic syndrome definers. A questionnaire was delivered to adult patients entering the nine health centres on November 2006 (n = 1211). During the year the ward personnel conducted intervention on patients with unhealthy habits. The 12-month follow up was conducted by mailings. Also clinical data of pre- and post-intervention values of metabolic syndrome definers were collected. For the analyses, intervention was divided into brief (≤ …

2015

Quality of life (QoL) is increasingly recognized as central to the broad construct of recovery in patients with substance use disorders (SUD). However, few longitudinal studies have evaluated changes in QoL after SUD treatment and included patients with SUD that were compulsorily hospitalized. This study aimed to describe QoL among in-patients admitted either voluntarily or compulsorily to hospitalization and to examine patterns and predictors of QoL at admission and at 6 months post treatment. This prospective study followed 202 hospitalized patients with SUD that were admitted voluntarily (N=137) or compulsorily (N=65). A generic QoL questionnaire (QoL-5) was used to assess QoL domains. R…

Effect of training level and blood flow restriction on thermal parameters: Preliminary study

2016

Abstract Training with blood flow restriction could lead to an effect on skin temperature. Additionally, this effect could be higher in people with lower physical fitness level due to their lower capacity of heat loss. The aim of this preliminary study was therefore to evaluate the effects of training experience on the acute and chronic thermal skin responses after performing exercise with and without blood flow restriction. The study included ten men, of these, five were trained. All subjects performed tests and re-tests for maximum strength (1 repetition maximum) through unilateral leg extensions (right thigh at 45 ± 6.7 kg and left thigh at 45.5 ± 8.1 kg, p > 0.05). The protocol consiste…
