*n values indicate number of patients for which data were available in each category. CT, Chlamydia trachomatis; LGV, lymphogranuloma venereum; IQR, interquartile range; OR, odds ratio; ND, no data were available; NP, not performed. Blank cells indicate not applicable.
†Multivariable analysis adjusted for age and location.
‡Glasgow patients were excluded from all univariable and multivariable analyses because they do not routinely report to the Genitourinary Medicine Clinic Activity Dataset.
