Screening of adolescents for testicular cancer-a nationwide retrospective cohort study.
Article in American journal of epidemiology, 2026. 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
Testicular cancer is the most common malignancy in males aged 15 to 34 years, yet the value of screening asymptomatic adolescents remains unclear. We conducted a nationwide, population-based cohort study of 300 793 Israeli males aged 16 to 21 years who underwent clinical testicular examinations between 2012 and 2021 before mandatory military service, generally lasting 3 years. Participants were followed for incident testicular cancer during their service. Screening involved inspection and palpation by general physicians, with referrals to ultrasound and urologists for suspicious findings. During 1 172 603 person-years of follow-up, 43 cases of testicular cancer were identified (incidence rate, 3.67 per 100 000 person-years). The sensitivity of screening was 66.7% and 40% at 6 and 12 months, respectively. Each cancer detected required screening 75 198 adolescents and included 176 ultrasound tests and 112 specialist consultations. Most cancers were diagnosed at stage I regardless of screening. The low sensitivity, high number needed to screen, frequent unnecessary evaluations, and low incidence of testicular cancer suggest that routine screening of asymptomatic adolescents is ineffective. These findings do not support routine testicular cancer screening in this population.
