1 · What the graph read from 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.

2 · The registry

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 evaluate safety and clinical response of Low-intensity Shockwave Therapy (Li-SWT) for the treatment of erectile dysfunction. MATERIALS &

methodsA single-institution, 2 arm, phase II randomized clinical trial was conducted between February 2017 and April 2019. Patients were randomized into 2 groups, with Li-SWT delivering a total of 3,600 shocks over 5 days (720 once a day, Group A) or over 2 weeks (600 once a day, 3 times a week, Group B). Patients were evaluated for the safety of therapy and completed the International Index of Erectile Function-Erectile Function domain and the Erectile Hardness Scale assessment at baseline, and at 1, 3, and 6 months visits.

resultsAmong 87 evaluable patients, 45 and 42 were allocated to Groups A and B treatment schedules, respectively, and 80 patients (40 per group) completed the 6-month evaluation. No adverse events were reported during treatment or during follow-up. There were statistically significant (P < .05) improvements in International Index of Erectile Function-Erectile Function score (mean increase of 2.7 [95% CI = 1.2, 4.2] and 2.7 points [95% CI = 1.4, 4.1] for Groups A and B, respectively) and in Erectile Hardness Scale (mean increase of 0.6 points (95% CI = 0.3, 0.8) and 0.5 (95% CI = 0.2, 0.8) for Groups A and B, respectively) at 6 months, with no differences between groups.

conclusionNo difference in outcomes was found when Li-SWT 3,600 shocks were delivered over 1 or 2 weeks at 6 months follow-up and both schedules were safe with no adverse events during or after treatment. Further trials with longer follow-up and sham arm will provide valuable information regarding treatment efficacy and durability. Patel P, Katz J, Lokeshwar SD, et al.
