The association of smoking with urinary and sexual function recovery following radical prostatectomy.
Observational study in BJU international, 2025. 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 investigate the association of smoking with post-prostatectomy functional recovery in a large population-based cohort using standardised outcome measures. PATIENTS AND
methodsWe conducted a cohort study and reported findings according to the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines. We used a registry with prospectively gathered patient-reported outcome measures (PROMs) regarding health and morbidity. We included all men who underwent radical prostatectomy (RP) for localised prostate cancer, without (neo)adjuvant hormone or radiotherapy treatment. In our analysis, we compared Expanded Prostate Cancer Index Composite-26 (EPIC-26) scores between people who had ever smoked and those who had not during 24 months' follow-up. We identified significant confounders by means of a causal directed acyclic graph, adjusted for these, and performed subgroup and sensitivity analyses.
resultsIn total, 2676 patients were included in the analysis. PROM data were available for 61% of the total 4356 otherwise eligible participants. Multivariable regression analysis showed that patients who had ever smoked (ever smokers) scored 11 points lower for sexual function (95% confidence interval -15.0, -7.0) compared to never smokers during 24 months' follow-up. Subgroup analysis showed that individuals with baseline scores above 80 were more at risk of sexual function loss. Urinary incontinence scores were similar between ever smokers and never smokers.
conclusionSmoking was associated with lower sexual function scores in the first 2 years after RP, but not with changes in urinary incontinence outcomes.
