Laboratory analyses were performed blind to case and control status. We compared mean levels of analytes between cases and controls with t tests. We also estimated risks using odds ratios and 95% confidence intervals (SAS 9.1). Models were constructed to assess effects associated with catego- ...

I don't think you will find something like a "best practices permission assignment on nested folders" because it depends from case to case and what you would like to achieve with those resources. There are some general best practices guidelines when it comes to assigning permissions but it ...
Data analysis was conducted using SAS (version 9.4, SAS Institute Inc., Cary, NC). Secondary Analysis We also investigated the risk of each disease of the five major components of MACE, including HF, MI, stroke, arrhythmia and cardiovascular death. Risk-set sampling was done independently for...
Data sets were constructed and analyzed by using SAS (version 9.3; SAS Institute Inc) and STATA (version 13; StataCorp) statistical software, respectively. We defined tests with 2-sided P < .05 as significant. Sensitivity and Subgroup Analysis Multiple additional analyses were performed. Firs...
All statistical analyses were carried out using the SAS statistical software package 9.4 (SAS Institute, Cary, NC) or STATA statistical software, release 14.2 (STATA Corp, College Station, TX). All tests were two-sided and were considered significant at a p value < 0.05. Results The Nes...
We conduct PS-matching using nearest neighbor matching method and baseline covariates in 1:5 ratio. A p-value < 0.05 was considered significant. All statistical analyses were performed using SAS software, version 9.4 (Cary, NC, USA)....
