*No significant age trends were observed in MSM for any of the infections (T. vaginalis; no observed cases, M. genitalium; p=0.132 and C. trachomatis; p=0.101). Except for C. trachomatis, where the infection was more prevalent in the younger age groups (p≤0.001), no significant age trends were observed in MSW either (T. vaginalis; p=0.235 and M. genitalium; p=0.596).
†Significant differences between MSM and MSW were found for T. vaginalis infection (p=0.007) and for C. trachomatis infection (p=0.027), but not for M. genitalium (p=0.131).
