The influence of age and the presence of prostate cancer on prostate volume, PSA and PSA density.
Article in BJU international, 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
objectiveTo assess prostate volume (PV) changes with age in symptomatic and asymptomatic men with and without clinically significant prostate cancer (csPCa). In symptomatic patients, we additionally analysed the effect of age and csPCa on PSA and PSA-density (PSA-D) and compared these to current National Institute for Health and Care Excellence (NICE) recommended PSA age-range thresholds. Patients and Methods This single-centre retrospective cross-sectional study included 2512 men: 760 asymptomatic, disease-free men and 1752 patients referred on a PCa diagnostic pathway. Magnetic resonance imaging-derived whole-gland PV was recorded for all patients. A machine-learning pipeline with k-fold cross validation modelled relationships between PV and age.
resultsIn asymptomatic men (median PV 25.4 mL), the mean PV per age-group increased non-linearly with age, from 18.7 mL at an increase of 0.10 mL/year aged 18 years, to 41.3 mL at 0.68 mL/year aged 89 years, with increased rate of change from the age of 48.9 years. Significant positive relationships were shown between PSA and age in patients with and without csPCa (r
conclusionIn asymptomatic men, PV changed non-linearly with age. Age-related PSA thresholds are supported; however, a static PSA-D threshold of 0.15 ng/mL
