Efficacy and safety of dutasteride with tadalafil add-on therapy in patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia.
Article in BMC research notes, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveTo evaluate the efficacy and safety of add-on therapy with the phosphodiesterase type 5 inhibitor tadalafil in Japanese men with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) treated with dutasteride.
resultsTwenty-four patients were enrolled. The participants had a median age of 71.0 (64.8-73.0) years and a median prostate volume of 37.3 (29.7-41.8) mL as measured using transabdominal sonography. The efficacy indicators, such as International Prostate Symptom Score (IPSS), quality of life (QOL) score, night-time urinary frequency, and night-time maximum voided volume, improved significantly at 4 weeks, and the effects lasted until 24 weeks (IPSS: 9.5 vs. 17.0, QOL: 2.0 vs. 4.0, nocturia: 2.0 vs. 2.0, night-time maximum voided volume: 290.0 vs. 240.0 mL). Overactive bladder symptom score (OABSS) and sexual health inventory for men (SHIM) significantly improved at 12 weeks, and the effects lasted until 24 weeks (OABSS: 3.0 vs. 5.0, SHIM: 11.0 vs. 7.5). However, maximum urine flow and residual urine volume showed no improvement at any point. Adverse events occurred in two cases. Taken together, add-on therapy with tadalafil was effective for patients with LUTS/BPH resistant to dutasteride monotherapy. In addition, this therapy was not associated with severe adverse events.
