Meta-analysis of the efficacy and safety of combination of tamsulosin plus dutasteride compared with tamsulosin monotherapy in treating benign prostatic hyperplasia.
Synthesis in BMC urology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
backgroundWe performed a meta-analysis to confirm the efficacy and safety of the combination of tamsulosin plus dutasteride compared with tamsulosin monotherapy in treating benign prostatic hyperplasia (BPH) during a treatment cycle of at least 1 year.
methodsRandomized controlled trials were searched by using MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. Systematic review was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-analyses. The data was evaluated and statistically analyzed by using RevMan version 5.3.0.
resultsFive studies including 4348 patients were studied. The analysis found that the combination group was significantly greater effect in international prostate symptom score (mean difference [MD], - 1.43; 95% confidence interval [CI], - 2.20 to - 0.66; P = 0.0003), prostate volume (MD, - 10.13; 95% CI, - 12.38 to - 7.88; P < 0.00001), transitional zone volume (MD, - 3.18; 95% CI, - 3.57 to - 2.79; P<0.0001), maximum urine flow rate (MD, 1.05; 95% CI, 0.82 to 1.29; P < 0.00001), prostate specific antigen (MD, - 0.54; 95% CI, - 0.80 to - 0.29; P < 0.0001) and post-void residual volume (MD, - 3.85; 95% CI, - 4.95 to - 2.76; P < 0.00001) compared with the tamsulosin group. In terms of safety, including adverse events (odds ratio [OR], 2.06; 95% CI, 1.34 to 3.17; P = 0.001), erectile dysfunction (OR, 2.24; 95% CI, 1.73 to 2.92; P < 0.00001), ejaculation disorder (OR, 3.37; 95% CI, 1.97 to 5.79; P < 0.0001), retrograde ejaculation (OR, 2.30; 95% CI, 1.08 to 4.93; P = 0.03), decreased libido (OR, 2.25; 95% CI, 1.53 to 3.31; P < 0.0001) and loss of libido (OR, 3.38; 95% CI, 1.94 to 5.88; P<0.0001), the combination group showed poor tolerance than the tamsulosin group with the exception of dizziness (OR, 1.16; 95% CI, 0.75 to 1.80; P = 0.50). The combination group significantly reduced the risk of clinical progression than the tamsulosin group especially in incidence of BPH-related symptom progression (OR, 0.56; 95% CI, 0.46 to 0.67; P < 0.00001) and acute urinary retention (OR, 0.61; 95% CI, 0.38 to 0.98; P = 0.04).
conclusionThe combination of tamsulosin plus dutasteride provides a preferable therapeutic effect for BPH with a higher incidence of sexual side effects, but combination-therapy can markedly reduce risk of BPH-related symptom progression and acute urinary retention relative to tamsulosin monotherapy.
