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
backgroundα-1 blockers and dutasteride are widely used as agents to treat benign prostatic hyperplasia (BPH); the impact of these drugs on prostatic inflammation is still unclear. Herein, we investigated the impact of α-1 blockers and dutasteride treatment of BPH in terms of the degree of prostatic inflammation. MATERIALS AND
methodsTissue specimens were obtained from 143 BPH patients who were administered α-1 blockers up until their operation. Thirty-three of the patients had also been treated with dutasteride before the procedure. The degree of prostatic inflammation was quantified histologically by the ratio of high endothelial venule (HEV)-like vessels. We divided this retrospective cohort into α-1 blocker monotherapy and combination therapy (α-1 blockers + dutasteride) groups and evaluated clinical parameters of the two groups in relation to the degree of chronic prostatic inflammation. At the same time, we assessed factors exacerbating chronic prostatic inflammation.
resultsComparison of the monotherapy and combination therapy groups showed no significant differences in the parameters of the urodynamic study or degree of chronic prostatic inflammation, whereas the IPSS total score, voiding subscore, nocturia, intermittency, weak stream, and straining were significantly lower in the combination than the monotherapy group. The duration of α-1 blockers administration was not correlated with the ratio of HEV-like vessels, while that of dutasteride was strongly correlated (correlation coefficient = 0.595; p < 0.001). Multiple regression analysis demonstrated that the duration of dutasteride administration was a key factor exacerbating the degree of chronic prostatic inflammation.
conclusionsThe present study showed that despite their ameliorating effect on prostatic hyperplasia, dutasteride contributed significantly to chronic prostatic inflammation.
