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

objectiveTo review recent literature pertaining to collagenase clostridium histolyticum (CCh)and other intralesional (IL) therapies for the treatment of Peyronie's disease (PD).

methodsA systematic search of literature was performed using MEDLINE and PubMed.'Peyronie's Disease Clostridium Histolyticum', 'Peyronie's Disease Intralesional', 'Peyronie'sDisease Causes', and 'Atypical Peyronie's Disease' were used as query entries. Inclusion criteriarequired English text from 1980 onwards and have a full text available. Records were reviewed for study power, accuracy, and relevance to our research topic. The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria.

resultsRecent literature supports the notion that CCh is the most effective IL treatment forpatients with typical and atypical PD. The capstone CCh study was the IMPRESS trial thatshowed a 34% reduction in curvature with a mean (SD) - 17.0 (14.8)° reduction with IL CCh,while men in the placebo saw an average 18.2% decrease in penile bend with a mean (SD) - 9.3 (13.6)° per person (P < 0.001). A shortened protocol for IL CCh treatment offered a 31.4%reduction in curvature, while decreasing cost and office visits, potentially increasing patientcompliance. Lastly, literature shows CCh is used most in atypical cases, with ~64.8% of patients being treated with CCh, probably because of the high efficacy and safetyprofile that it offers. Serious complications associated with CCh include urethralinjury, corporal rupture, and penile fracture.

conclusionSince the approval of CCh by the United States Food and Drug Administration in2013, it has been a staple in the treatment of PD, and here we report the continuedsuperiority of this therapy. CCh is an effective, minimally invasive option in most PDpopulations; however, recent changes have made CCh unavailable for commercial use outside the United States, impacting many patients who have previously benefited.
