a
Statistically significant (P < 0.05; chi-squared, 2-tailed test) decrease in periorbital injuries in preadolescent compared with adolescent and adult baboons.
b
Statistically significant (P < 0.05; chi-squared, 2-tailed test) increase in scalp injuries in preadolescent compared with adolescent and adult baboons.
c
Statistically significant (P < 0.05; chi-squared, 2-tailed test) increase in male compared with female baboons.
d
Statistically significant (P < 0.05; chi-squared, 2-tailed test) increase in prevalence of IED and PS in baboons with periorbital compared with scalp or muzzle injuries.
