Article in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe aim of this study was to analyze the prevalence of common sexually transmitted infections, including Ureaplasma urealyticum (UU), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and herpes simplex virus (HSV), in Hangzhou, China.
methodsAn analysis was conducted on 12,505 patients who visited the outpatient department of Tongde Hospital of Zhejiang Province from 2018 to 2024. Urinary and reproductive swabs were collected, and the deoxyribonucleic acid (DNA) contents of UU, CT, NG, and HSV 1/2 were detected via real-time polymerase chain reaction (PCR).
resultsAmong 12,505 outpatients, the age-adjusted prevalence was 30.93% for UU, 10.33% for CT, 11.51% for NG, and 10.64% for HSV. UU infection is prevalent among individuals aged 20 to 59, whereas CT and NG infections are most commonly observed in the 15 to 19 age group. UU and HSV infections primarily affected women, whereas CT and NG infections were more prevalent among men. The prevalence of HSV-2 infection was significantly positively correlated with age. Additionally, co-infection with UU and CT (16.61‰) was the most prevalent. UU was positively associated with CT, CT was positively associated with NG, while UU was negatively associated with NG. The age-adjusted prevalence of CT and NG, as well as the age-adjusted prevalence of UU in women, declined significantly in 2020 and then gradually increased thereafter.
conclusionsThis study furthers understanding of the epidemiological characteristics of UU, NG, CT, and HSV among outpatients in Hangzhou, providing a scientific basis for optimizing regional screening strategies and formulating effective prevention and control plans. CLINICAL TRIAL: Not applicable.
