Impact of Age, Marital Status, Smoking, and Alcohol Consumption on Urinary and Sexual Function in Prostate Cancer Patients Treated With Radical Prostatectomy: A Prospective Cohort Study.
Article in Urology, 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 examine the impact of age, marital status, smoking status, and alcohol use on urinary and sexual function up to 1 year post-radical prostatectomy (RP) among men with prostate cancer.
methodsParticipants were recruited from the Prostatectomy, Incontinence, and Erectile dysfunction study. Patient characteristics were assessed at baseline. Urinary and sexual function were assessed using the Expanded Prostate Cancer Index Composite-50 at baseline and 5 weeks, 6 months, and 12 months post-RP. Mean urinary and sexual function scores were calculated for each time point by patient characteristics.
resultsThe cohort consisted of 311 and 286 men for urinary function and sexual function, respectively. Urinary function: At baseline, married men had significantly higher urinary function scores (P = .027). By 6 months post-RP, older (vs younger, P = .044) and unmarried men (vs married, P = .008) had significantly worse urinary function. By 12 months post-RP, these differences disappeared, with all groups returning to levels approaching baseline. Sexual function: At baseline, participants who were younger (P <.001), never-smokers (P <.001), and more frequent consumers of alcohol (P = .021) had significantly higher sexual function scores. Small improvements in sexual function occurred at 6 months post-RP. By 12 months post-RP, sexual function did not recover to baseline levels for any group and was significantly lower for older (P <.001), unmarried (P <.025), and ever-smoker participants (P = .002).
conclusionUrinary function scores recover to levels approaching baseline by 12 months post-RP. Sexual function scores do not recover to baseline levels by 12 months post-RP for any group and are lower for participants who are older, unmarried, or smoke.
