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
backgroundMale-factor infertility contributes substantially to the burden of infertility, yet evidence on semen abnormalities and their associated factors in Uganda remains limited. This study assessed the prevalence, patterns, and factors associated with abnormal semen values among men seeking fertility services in Eastern and Central Uganda.
methodsA cross-sectional study was conducted among 155 men attending Jinja Regional Referral Hospital, Kayunga Regional Referral Hospital, and Healingway Diagnostic and Fertility Centre between September 2025 and January 2026. Semen analysis was performed using World Health Organization criteria. Factors associated with abnormal semen values were assessed using bivariable and multivariable logistic regression analyses.
resultsOverall, 52 of 155 participants had at least one abnormal semen parameter, giving a prevalence of 33.5% (95% CI: 26.5-41.4). The prevalence did not differ significantly across study sites (p = 0.841). Teratozoospermia (42.3%) and asthenozoospermia (38.5%) were the most common abnormalities, followed by hypospermia (26.9%), necrozoospermia (25.0%), oligozoospermia (23.1%), and azoospermia (23.1%). Hypertension (AOR = 5.23; 95% CI: 1.10-24.93), diabetes mellitus (AOR = 4.82; 95% CI: 1.85-12.57), medication use (AOR = 2.73; 95% CI: 1.11-6.71), history of mumps infection (AOR = 5.29; 95% CI: 1.25-22.31), and occupational hazard exposure (AOR = 4.23; 95% CI: 1.60-11.13) were independently associated with abnormal semen parameters.
conclusionsApproximately one in three men seeking fertility services in Eastern and Central Uganda had at least one abnormal semen parameter, with abnormalities in sperm morphology and motility being the most common findings. Hypertension, diabetes mellitus, medication use, history of mumps infection, and occupational hazard exposure were associated with abnormal semen parameters. Assessment of medical conditions, previous infections, medication use, and occupational exposures may therefore be useful when evaluating men presenting with infertility.
