A limitation was that our sample of gender-referred children was relatively small.
When the sample characteristics of gender, age, brain pH, postmortem interval (PMI), and sample refrigeration interval (RFI) were included individually as a covariate in UNPHASED analysis, the Wald test indicated no significant covariate effect on β2S1 or β2S2 expression.
Table 1 gives an overview of sample characteristics of gender, age, and education across the assessment conditions.
In a small sample of 22 gender dysphoric girls and 147 control girls, the gender dysphoric girls were significantly more likely to be early born, especially in relation to their sisters but not their brothers.
Focus group participants, in contrast to household survey participants, offered a more representative sample of the gender, tribes, and geographic distribution of pastoralists in the study.
One sample of unknown gender was omitted from the statistics.
Heterogeneity was sought by purposively sampling equal numbers of participants from a younger age group (18 21 years) and older age group (22 25 years), as well as a sample of each gender.
Variability in gene expression was observed between samples, independently of gender, age or the status of the patient (normal, OA or RA) (data not shown).
For each study the literature reference, wellbeing measure, name of the study cohort, age of the sample, gender of the sample, sample size (per zygosity if provided), twin (-family) correlations, and estimates of standardized variance components are provided.
