Molecular detection of causative agents of sexually transmitted infections within the samples.

PCR Target	Numbers and Proportions of Detections n/n (%)	Mean (SD) of the Measured CT Values	Median (Min., Max.) of the Measured CT Values
Treponema pallidum	0/268 (0%)	n.e.	n.e.
Chlamydia trachomatis screening	3/268 (1.1%)	31.3 (2.6)	30 (29, 35)
Chlamydia trachomatis differentiation: LGV-associated	0/268 (0%)	n.e.	n.e.
Chlamydia trachomatis differentiation: non-LGV-associated	3/268 (1.1%)	34.3 (1.7)	35 (32, 36)
Mycoplasma genitalium	0/268 (0%)	n.e.	n.e.
Neisseria gonorrhoeae *	5/268 (1.9%)	Please see below!	Please see below!
multi-copy opa genes	5/268 (1.9%)	31.8 (2.2)	33 (29, 34)
porA pseudogene	5/268 (1.9%)	34.0 (2.6)	33 (31, 38)

PCR = polymerase chain reaction. SD = standard deviation. CT = cycle threshold. Min. = minimum. Max. = maximum. n.e. = not estimable. LGV = lymphogranuloma venereum. * In two further instances, N. gonorrhoeae could not be confirmed because of negative porA-pseudogene PCR in spite of positive opa gene PCR with Ct values of 32 and 34, respectively.
