Comparison of the effects of extracorporeal shock wave therapy and a vacuum erectile device on penile erectile dysfunction: a randomized clinical trial.
Trial report in Medicine, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundThis randomized clinical trial (October 2012-December 2013) compared extracorporeal shock wave therapy (ESWT) and a vacuum erectile device (VED) for management of erectile dysfunction (ED).
methodsConsecutive Chinese patients (20-55 years) with ED, abnormal nocturnal penile tumescence and rigidity (NPTR), and international index of erectile function-5 items (IIEF-5) score <22 were randomized to receive ESWT or VED (twice weekly, 4 weeks). Primary outcomes were treatment efficacy and success rate 4 weeks after completion of therapy. Secondary outcomes included changes in IIEF-5 score, sex encounter profile (SEP) score, erection hardness score (EHS) and NPTR assessments 4 weeks post-therapy. All enrolled patients (n = 30 per group) completed the study. At baseline, age, IIEF-5 score, SEP score, EHS, and NPTR assessments were similar between groups.
resultsFour weeks post-therapy, IIEF-5 score increased in the ESWT (15.03 ± 3.00 vs. 11.60 ± 2.28) and VED (15.10 ± 3.06 vs. 11.53 ± 2.27) groups, as did SEP score, EHS, and NPTR measures (all P < .05). Efficacy in the ESWT and VED groups was excellent in 10% and 13.3%, respectively, and moderate in 63.3% and 53.3%, respectively. Treatment success rate in the ESWT and VED groups was 73.3% and 67.7%, respectively.
conclusionVED use and ESWT have comparable efficacies in the treatment of ED in Chinese patients.
