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
purposeTo assess adherence to combination therapy comprising α-adrenergic blocker (AB) and 5α-reductase inhibitor (5ARI) for benign prostatic hyperplasia (BPH) in a real-world setting and whether lower urinary tract symptoms (LUTS) will relapse after discontinuing one medication from long-term combination therapy.
methodsBPH/LUTS patients receiving initial AB +5ARI combination therapy for at least 1 year between January 2012 and January 2017 were retrospectively analyzed. The patients were classified into DC-AB group (n = 65, AB discontinued) and DC-5ARI group (n = 77, 5ARI discontinued) and followed up. Clinical effects were assessed at baseline and annually using the International Prostatic Symptoms Score (IPSS), quality of life (QoL) index, total prostate volume (TPV), maximal flow rate (Qmax), and prostate-specific antigen (PSA) level.
resultsOf total 1783 patients, 809 (45.4%) patients were identified with more than 1-year combination therapy. After withdrawal of one medication from combination therapy, the TPV progression (27.6% vs. - 10.8%; P < 0.001) and the requirement for prostate surgery (14.3% vs. 6.1%; P = 0.038) were significantly higher in the DC-5ARI group than in the DC-AB group. The rate of resuming combination therapy was significantly higher in the DC-5ARI group than in the DC-AB group (38.9% vs. 23.0%; P = 0.009).
conclusionsAdherence to combination BPH therapy is relatively low. Although patients adhered to combination therapy for more than 1 year, a higher risk of requiring prostate surgery or resuming combination therapy was observed in patients who discontinued 5ARI.
