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

objectivesTo compare two different specimen extraction sites (SES) (off-midline [OM] vs. supraumbilical) for the incidence of incisional hernias (IHs) and to evaluate different risk factors for their occurrence after robot-assisted radical prostatectomy. PATIENTS AND

methodsIn our clinic, prior to June 2019, SES were supraumbilical; thereafter, they were OM. The primary endpoint was to determine the need for IH repair according to the chosen SES. Additionally, we evaluated possible risk factors. Statistical analysis was performed with the Mann-Whitney U test, Chi-squared, binary and multiple logistic regression analysis, and log-rank testing.

resultsData from 914 consecutive patients (April 2018-September 2020) were used for the final analysis; of these, 439 (48%) had a supraumbilical and 475 (52%) an OM SES. After a median follow-up of 35.0 months, 50 (5.5%) patients developed an IH: 42 (9.5%) from the supraumbilical group and eight (1.7%) from the OM group (P < 0.001, odds ratio 5.495; 95% confidence interval 2.42-12.48). Median time to IH repair was 7.9 months: 0.5 in the OM and 10.1 in the supraumbilical group (P = 0.026). There were no other associations with clinico-pathological patient data.

conclusionThe SES in robot-assisted radical prostatectomy seems to play an important role in the development of postoperative IHs, with the OM approach potentially offering an advantage. Additionally, IHs appear to occur earlier with an OM than with a supraumbilical approach.
