These data were used to produce the results of the meta-analysis of the following article: "Asymptomatic infections with Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) among women in low- and middle-income countries: A systematic review and meta-analysis".

The database contains all the published articles included in the systematic review and meta-analysis.

We selected studies published between 1 January 2000 and 31 December 2022, in English and French. We included studies that tested for STIs using genital or urine specimens. We kept studies that used NAATs for the diagnosis of CT, NG, and TV. For TV, we also included articles that used InPouch® or performed wet mount microscopy immediately after collection, as these techniques showed fair sensitivity and specificity and remain common detection methods in LMICs. We selected studies where the investigator actively asked about at least one symptom, or where participants self-reported symptoms. We excluded articles in which authors assumed the absence of symptoms in the entire study population without collecting such information. Finally, we excluded articles when “asymptomatic” was defined as the absence of clinical signs as reported by the healthcare provider rather than by the women as we intended a participant-centred approach.

Some articles appear multiple times: this is either because they explored multiple pathogens (e.g., Chlamydia trachomatis and Trichomonas vaginalis) or they have recruited participants at different sites (e.g., antenatal care and family planning). Each line describes the study population or subpopulation's characteristics.
