The same problem occurs if I use an alternative method of prediction: gllapred newvar, xb I have checked to see that I have the same variables in my dataset as in the estimated model. Variable names are in the correct case. The internal order of the variables in my second dataset is ...

Post-resuscitation care after out-of-hospital cardiac arrest (OHCA) is challenging due to the threat of organ failure and difficult prognostication. Our aim was to examine whether urine biomarkers could give an early prediction of acute kidney injury (AKI) and outcome. Methods This was a prospect...
Performance of the DELFIA Express sFlt-1/PlGF ratio <50 to rule-out pre-eclampsia within seven days was comparable to the PROGNOSIS study (Prediction of Short-Term Outcome in Pregnant Women with Suspected Preeclampsia Study), a prospective, multicentre, observational study of performance of assays ...
directed acyclic graph of the assumptions underpinning the analytical model: the aim of covariate adjustment was to minimise confounding influences on the association between air pollution exposure and cognitive performance, rather than to construct a multivariable risk prediction model for cognitive outcome...
Stata version 15.1 (StataCorp LLC; College Station, Texas) and RStudio version 1.1.423 (RStudio Inc; Boston, Massachusetts) were used for all analyses. RESULTS There were 3013 Medicare PDPs in 2009 and 2150 PDPs in 2017 included in our sample (eAppendix Figure 1). Over this period, the...
Bioclimatics is an important determinant of habitat suitability for the cat flea and its hosts because it encompasses the effects of both climate and vegetation factors [20,33]. However, as a limitation for a more in-depth knowledge of a whole bioclimatic area, more sample points are required...
The outcomes were gastrointestinal cancer/colorectal cancer as a cause of IWL, while the predictor variable was ferritin. Results were expressed as frequencies for categorical variables, and median and extremes for non normal continuous variables. Stata 11 (StataCorp, College Station, Texas, USA) was...
“opt-in” into the survey. This may have excluded respondents who are less motivated to take part in the survey. The survey was mostly promoted through online media and LGBT organisations which could affect the sample composition: groups with higher access to- and use of internet (young, ...
