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

BACKGROUND AND

objectivesTo examine the association between hospital surgical volume and perioperative mortality of pelvic exenteration performed for gynecologic malignancies.

methodsA population-based retrospective study utilizing the Nationwide Inpatient Sample was conducted to examine pelvic exenteration for gynecologic malignancies from 2001 to 2011. Annualized hospital surgical volume was defined as the average number of procedures a hospital performed per year in which at least one case was performed, and this was correlated to perioperative mortality.

resultsA total 1912 exenterations performed at 181 centers were included. Nearly two thirds of exenteration-performing centers had a minimum surgical volume of one case per year (121 centers, 66.9%). Perioperative mortality rate was 1.8%. In multivariable analysis surgical volume remained an independent factor for perioperative mortality (adjusted-odds ratio 0.21; 95% confidence interval, 0.09-0.49; P < .001). Perioperative mortality rates were 3.7% for the centers with minimum surgical volume (1 exenteration a year), 1.4% for the centers performing more than one but two or less exenterations a year, and 0% for the top decile centers (>2 exenterations a year), respectively (P < .001).

conclusionPelvic exenteration for gynecologic malignancy is a rare surgical procedure with most hospitals performing few cases annually. A higher surgical volume of pelvic exenteration was associated with lower perioperative mortality.
