Table 3. Sex-based comparisons of age by species.
Quantile regression for 25th, 50th, 75th, and 85th percentiles. Regression models adjusted for primate location (data source). Distribution of ages by sex were assessed using the Kolmogorov Smirnov test. Complete data used for analyses (natural or clinical deaths) with no censoring.
