Prevalence of Mycoplasma Penetrans in Urethral and Rectal Specimens from Men Attending an STI Clinic.

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
Mycoplasma penetrans has gained attention in relation to non-gonococcal urethritis (NGU), a syndrome where a significant proportion of patients have no identified aetiological agent. In this study, we estimated the prevalence of urethral and rectal M. penetrans in a male population attending a sexually transmitted infection (STI) clinic in Copenhagen, Denmark. Specimens were assessed using M. penetrans-specific real-time polymerase chain reaction (PCR). Demographic characteristics and clinical symptoms were extracted from patient records. A total of 704 urethral specimens and 223 rectal specimens from 721 individual male patients were included. The prevalence of urethral and rectal M. penetrans was 0.3% and 2.7%, respectively. Overall, the prevalence among men who have sex with men (MSM) was 3.6%, significantly higher than in men who have sex with women (p < 0.001). Among MSM, a higher number of partners was associated with M. penetrans infection (p = 0.008). No association was found between the presence of M. penetrans and clinical symptom status, and its pathogenic potential remains unclear.
