A new approach to define acceptance limits for hematology in external quality assessment schemes.
their corresponding assigned value (U-scores) was modeled by means of an adaptation of Thompson’s “characteristic function”. Quantile regression was used to investigate the percentiles of the U-scores for ...
Disability weights for infectious diseases in four European countries: comparison between countries and across respondent characteristics.
Methods: We analyzed paired comparison responses of the European DW study by participants’ characteristics with separate probit regression models. To evaluate the effect of participants’ characteristics, we ...
High relative humidity pre-harvest reduces post-harvest proliferation of Salmonella in tomatoes.
a significant effect of harvest time. We explored the data from two previously published and one unpublished experiment using regression trees, which allowed overcoming the interpretational difficulties of ...
Effect of allergic bronchopulmonary aspergillosis on FEV1 in children and adolescents with cystic fibrosis: a European Cystic Fibrosis Society Patient Registry analysis.
of ABPA (main explanatory variable) on FEV1 while controlling for other prognostic factors, a linear mixed effects regression model was applied. RESULTS: In 2008, the mean (± SD) FEV1 percent predicted ...
Mapping EQ-5D utilities to GBD 2010 and GBD 2013 disability weights: results of two pilot studies in Belgium.
developed web-based EQ-5D-5 L questionnaire. The EQ-5D responses were translated into utilities using the model developed by Cleemput et al. A loess regression allowed to map EQ-5D utilities to logit ...
Advanced Methods for Dose and Regimen Finding During Drug Development: Summary of the EMA/EFPIA Workshop on Dose Finding (London 4-5 December 2014).
for drug developers and regulators were presented. These methods are described in the present report: they include five advanced methods for data analysis (empirical regression models, pharmacometrics ...
Does air pollution trigger suicide? A case-crossover analysis of suicide deaths over the life span.
applied conditional logistic regression models adjusted for duration of sunshine and day of the week to obtain odds ratios (OR) and their 95% CI for an increase of 10 µg/m(3) in pollutant concentrations ...
Income-related inequality in smoking cessation among adult patients with cardiovascular disease: a 5-year follow-up of an angiography intervention in Luxembourg.
conducted in 2013/2014 among 4391 patients (of which 1001 patients were smokers) at the time of coronary angiography in 2008/2009. Four logistic regression models were applied. In three models, the predictor ...
Zona pellucida gene mRNA expression in human oocytes is related to oocyte maturity, zona inner layer retardance and fertilization competence.
main predictor of the fertilization capacity, next to IL-retardance and IL-thickness. Using stepwise regression analysis, IL-thickness combined with EFNB2 expression in CC and the patient’s ovarian ...
Clustering and diagnostic modelling of slimming aids based on chromatographic and mass spectrometric fingerprints
(i.e., Hierarchical Cluster Analysis (HCA)) and supervised techniques (i.e., Classification and Regression Tree (CART) and Partial Least Squares — Discriminant Analysis (PLS- DA)) were applied. The aim was ...
