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

purposeThis study aims to analyze patient demographics, hospital characteristics, and clinical risk factors which predict penile prosthesis removal. We also examine costs of penile prosthesis removal and trends in inflatable versus non-inflatable penile prostheses implantation in the USA from 2003 to 2015.

methodsCross-sectional analysis from Premier Perspective Database was completed using data from 2003 to 2015. We compared the relative proportion of inflatable versus non-inflatable penile prostheses implanted. We separated the prosthesis removal group based on indication for removal-Group 1 (infection), Group 2 (mechanical complication), and Group 3 (all explants). All groups were compared to a control group of patients with penile implants who were never subsequently explanted. Multivariate analysis was performed to analyze patient and hospital factors which predicted removal. Cost comparison was performed between the explant groups.

resultsThere were 5085 penile prostheses implanted with a stable relative proportion of inflatable versus non-inflatable prosthesis over the 13-year study period. There were 3317 explantations. Patient factors associated with prosthesis removal were non-black race, Charlson Comorbidity Index, diabetes, and HIV status. Hospital factors associated with removal included non-teaching status, hospital region, year of removal, and annual surgeon volume. Median hospitalization costs of all explantations were $10,878. Explantations due to infection cost $11,252 versus $8602 for mechanical complications.

conclusionsThis large population-based study demonstrates a stable trend in inflatable versus non-inflatable prosthesis implantation. We also identify patient and hospital factors that predict penile prosthesis removal which has clinical utility for patient risk stratification and counseling.
