Prostate Cancer Among Patients Presenting with Obstructive Lower Urinary Tract Symptoms at a Tertiary Hospital in South Western Uganda.
Article in Research and reports in urology, 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
Background: Prostate cancer is currently the second commonest male cancer both globally and in Uganda. Men are often tested after presenting with obstructive lower urinary tract symptoms (LUTS). We evaluated total prostate-specific antigen patterns (tPSA), digital rectal examination (DRE) findings, histological findings and prostate cancer rates among patients presenting to Mbarara regional referral hospital with obstructive LUTS. Methods: This was a cross-sectional study of 140 patients aged ≥50 with obstructive LUTS. Data on demographics and severity of LUTS was collected, plus the results of tPSA testing and DRE. Later, digitally guided transrectal tru-cut prostate biopsy was performed, if necessary. Analysis was done using SPSS (Statistical Package for Social Scientists), version 14. Confidence interval (CI) was set at 95% and P at 0.005. Results: The majority of patients had severe LUTS (n=103, 73.57%), with a median tPSA of 14.4 ng/mL. Ninety-nine patients experienced digitally guided transrectal tru-cut prostate biopsy (70.71%; Fisher's exact test = 0.001). DRE abnormalities were found in 57.14% (n=80) of participants and these carried a higher risk for prostate cancer diagnosis (risk ratio = 5.895; Fisher's exact test = 0.04; CI 95%: 1.59-21.822). The tru-cut biopsy positivity rate was high, at 46% (45/99; 95% CI: 30.1-46.3); all had prostate adenocarcinoma and the majority (77.78%, n=35) had a total Gleason score of 8 and above. Of those who had a malignancy, more than a quarter were between 60-80 years of age (37.8%, n = 17). There was no statistically significant relationship between LUTs and prostate cancer diagnosis (Fisher's exact test 2-sided = 0.84). Conclusion: Although severity of LUTS was not predictive of cancer, there was a high rate of advanced prostate cancer among study participants. DRE remains a valuable tool for identifying potential prostate cancer cases, especially in settings where PSA testing may be limited. Further research is needed to explore effective screening strategies and improve outcomes for men with prostate cancer in Uganda.
