While we found no evidence of a protective association between male circumcision (scale-up) and self-reported STIs among adolescent boys and men (15-49 years), it cannot be entirely excluded that scaling-up VMMC programmes had a protective effect on the prevalence of specific STIs.
"It cannot be entirely excluded" - dünner geht ja wohl nicht mehr.
