Ejaculation Frequency and Prostate Cancer: CAPLIFE Study.
Article in The world journal of men's health, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 2 of them syntheses 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
purposeTo evaluate the association between ejaculation frequency (EF) during four stages of life and prostate cancer (PCa) according to tumor aggressiveness, PCa stage, and urinary symptomatology. MATERIALS AND
methodsA total of 456 incident PCa cases histologically confirmed, and 427 controls aged 40-80 years from the CAPLIFE study were analyzed. This study is a population-based case-control study carried out in the south of Spain. Average EF was measured for: (1) 20s, (2) 30s, (3) 40s, and (4) one year before the interview. EF was categorized into: (1) 0-3, (2) 4, and (3) >4 ejaculations/month. Sociodemographic, lifestyle, and medical information were also collected. To estimate the association between EF and PCa, adjusted ORs (aORs) and 95% CIs were calculated by logistic regression models.
resultsA year before the interview, PCa cases ejaculated less frequently than the controls. An inverse association was observed between the EF a year before and PCa, aOR=1.64 (95% CI 1.03-2.61) for men with 4 ejaculations/month, and aOR=2.38 (95% CI 1.57-3.60) for men with 0-3 ejaculations/month, compared to men with >4. The association was higher for cases with ISUP 3-5 (aOR=2.76 [95% CI 1.34-5.67] for men with 0-3 ejaculations/month) or with a locally advanced-metastatic tumor (aOR=4.70 [95% CI 1.55-14.29]). Moreover, men with moderate urinary symptoms and 0-3 ejaculations/month had the highest risk, aOR=3.83 (95% CI 1.84-7.95).
conclusionsA low EF could be associated with a higher risk of PCa, especially for cases with ISUP 3-5 or with a locally advanced-metastatic tumor.
