The effect of the fire on PNP elephant population size and age structure was assessed by accounting for all mortalities (categorized according to age and sex) and comparing population size and age structure before the fire with that after the fire.
Based on the first-trimester urinary BPA concentrations for all the women, we then categorized each woman's first-trimester urinary BPA concentrations into surrogate tertiles.
We conducted tests for trends for all models of categorized data by treating the different categories as a single ordinal variable.
Tests for linear trend were performed for all models of categorized data by including the continuous, rather than the categorized, variable for each of the variables being modeled and all p values reported are two-sided.
The classification of the location is described as the reference parameter for categorizing all the dimensions and parameters of the problem.
The contributing cause of delirium for all participants was categorized using the Delirium Etiology Checklist (DEC) [ 46, 47].
For all cDNA sequences categorized by 'Significant Alignments on Mouse Genome', we also registered the exact chromosomal position in kilobases (starting from the top of the short arm).
Parental education level was reported using a six-point scale from 'no qualifications' to 'post-graduate', but for all analyses was categorized as 'university level education' vs 'not'not
For all analyses, we categorized HIV panel size as 0 10 (reference), 11 25, 26 50, 51 100, and >100 patients; and we categorized years of HIV care experience as ≤1 (reference), 2 5, 6 10, 11 20, and >20 years.
For all analyses, we categorized continuous miRNA expression levels as measured by qRT-PCR into two classes (<1, ≥1), using as cutoff the expression level of IGR-N-835 cell line taken as one 19.
