The statistical analysis without data of three priest participants with known physical ailments (priest, n = 7 vs. non-priest controls; n = 10). Values are expressed as median and interquartile range (25–75th percentile). A P value < 0.05 is statistically significant by Mann–Whitney U test. A P value < 0.05 is statistically significant by Mann–Whitney U test. Cohen’s guidelines for the effect sizes (r) for Mann–Whitney U test are that a large effect is 0.5, a medium effect is 0.3, and small effect is 0.1 [28]. (XLSX 41 kb
