Trichomonas vaginalis serostatus and prostate cancer risk in Egypt: a case-control study.
Article in Parasitology research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
Trichomonas vaginalis is one of the most common non-viral sexually transmitted infections (STIs) that has been associated with prostate cancer in some countries. This study aims to investigate if T. vaginalis infection can be a risk factor for prostate cancer in Egypt and its possible relationship with cancer prognostic factors and overall survival. Serum samples were collected from a total of 445 age-matched males; 126 with prostate cancer, 108 with bladder cancer, 91 with different types of cancers, and 120 healthy controls, and then analyzed by ELISA for detection of anti-Trichomonas IgG and prostate-specific antigen (PSA). The results revealed that only 8.3% of controls were seropositive for trichomoniasis, compared with 19% of prostate cancer patients (P = 0.015). There were positive associations between the levels of PSA and tumor stage with T. vaginalis IgG optical density scores among the seropositive cases (P < 0.001 and < 0.05, respectively). However, no significant correlations were detected between seropositivity of T. vaginalis and other prognostic factors or overall survival in those patients. In conclusion, chronic T. vaginalis infection may be associated with prostate cancer, but it does not seem that this STI aggravates the cancer status.
