Combined therapy with dutasteride and tadalafil vs dutasteride or tadalafil monotherapy in benign prostatic hyperplasia: a randomised phase III trial.
Trial report in BJU international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
objectivesTo evaluate the efficacy and safety of a fixed-dose combination (FDC) of dutasteride and tadalafil vs monotherapy in patients with benign prostatic hyperplasia (BPH). PATIENTS AND
methodsThis phase III trial enrolled 667 patients. After screening and washout, eligible patients were stratified by the baseline International Prostate Symptom Score (IPSS) and randomised (1:1:1) to receive FDC dutasteride 0.5 mg/tadalafil 5 mg (FDC 0.5/5 mg), dutasteride 0.5 mg, or tadalafil 5 mg for 48 weeks. The primary endpoint was the change in total IPSS from baseline to Week 48. Efficacy and safety were assessed at 4, 12, 24, 36, and 48 weeks.
resultsIn total, 619 patients were analysed for efficacy. The least squares (LS) mean (standard error [se]) change in total IPSS at 48 weeks from baseline was -9.49 (0.37) for the FDC 0.5/5 mg group vs -4.40 (0.37) for dutasteride 0.5 mg group (LS mean difference [LSMD] -5.09, 95% confidence interval [CI] -6.13 to -4.50; P < 0.001), and -9.53 (0.36) for the FDC 0.5/5 mg group vs -4.24 (0.37) for tadalafil 5 mg group (LSMD -5.29, 95% CI -6.30 to -4.27; P < 0.001). The FDC 0.5/5 mg group demonstrated the most pronounced improvement in quality of life. Although the maximum urinary flow rate and post-void residual volume improved in all groups, differences were not statistically significant. In the comparison between the FDC 0.5/5 mg and dutasteride 0.5 mg groups, the LSMD (95% CI) of change from baseline to Week 48 in the international index of erectile function - erectile function (IIEF - EF) total score was 4.03 (2.35 to -5.71) (P < 0.05). Among the 655 patients analysed for safety, treatment-emergent adverse events occurred in 32.88% (FDC 0.5/5 mg) vs 21.20% (dutasteride 0.5 mg) and 26.48% (tadalafil 5 mg), with few serious adverse events observed.
conclusionsThe FDC 0.5/5 mg demonstrated superior efficacy, and an acceptable safety profile compared with dutasteride and tadalafil monotherapies in patients with BPH.
