Distribution of potential aetiological agents recovered by PCR in urethral swabs of cases with urethral discharge and in asymptomatic controls. Percentages (and absolute numbers) with a given micro-organism are shown as well as odds ratios (OR) and adjusted odds ratios (AOR) and their 95% confidence intervals
| According to presence of NG | ||||
|---|---|---|---|---|
| Controls (n=100) | All cases of urethral discharge (n=410) | Urethral discharge positive for NG (n=274)† | Urethral discharge negativefor NG (n=136)¶ | |
| Odds ratios and p values correspond to comparisons between appropriate category of cases and controls; *p<0.05; ‡p≤0.001. | ||||
| †Adjusted in a logistic regression model for all controls and cases positive for NG, which included CT, TV, MG, UU, age, and number of sex partners in past 12 months. | ||||
