Lycopene intake and prostate cancer risk in men at high cardiovascular risk: a prospective cohort study.
Trial report in BMC medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundIntake of lycopene has been proposed as a protective dietary factor against prostate cancer development. Cardiovascular disease and prostate cancer share risk factors, which may modulate the effect of lycopene in high-risk individuals. This study aimed to examine the association between lycopene intake and prostate cancer risk in a Mediterranean population at high cardiovascular risk.
methodsA prospective cohort analysis was conducted among 2970 men aged 55-80 years at high cardiovascular risk from the PREDIMED trial, a multicenter study in Spain. Lycopene intake was assessed using repeated food frequency questionnaires. Prostate cancer cases were identified through medical records and death certificates. Cox proportional hazard models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) across lycopene intake quartiles.
resultsOver a mean follow-up of 5.8 years, 104 prostate cancer cases were identified. Participants in the highest quartile of lycopene intake had a significantly lower risk of prostate cancer than those in the lowest quartile (HR: 0.46; 95% CI: 0.23-0.95; p-trend = 0.035). A nonlinear dose-response relationship was observed, with a significant inverse association emerging at intakes above 4.9 mg/day (HR: 0.36; 95% CI: 0.13-0.98).
conclusionsHigher lycopene intake suggested a protective association with a lower incidence of prostate cancer in men at high cardiovascular risk. These findings support the role of lycopene-rich diets in prostate cancer prevention, which may be particularly relevant for high cardiovascular risk populations.
