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

introductionTraining and teaching are cornerstones in developing surgical skills. The present study aimed to compare intraoperative outcomes of colonic resections among fellows, consultants, and supervised trainees.

methodsData of consecutive colonic resections including demographics, surgical details, and intraoperative outcomes were recorded in a prospectively maintained institutional database. All procedures were standardized and divided in three groups according to the main surgeons experience (fellow or consultant) and whether the procedure was taught. After weighting by inverse treatment probability, intraoperative adverse events including reactive conversion, blood loss, and operating time were compared between these three groups.

resultsSix hundred sixty-four colectomies were analyzed between January 2014 and October 2017. Among them, 289 (43.5%) were taught. After weighted propensity score analysis, there was no difference between the three groups (fellow taken as reference), for intraoperative adverse event rate (odd ratio (OR) consultant 1.448 (IQR 0.728-2.878), p = 0.282; OR teaching 0.689 (IQR 0.295-1.609), p = 0.381), operating time (beta coefficient 0.76 (- 21.91-23.42), p = 0.947; beta coefficient - 10.79 (- 28.34-6.75), p = 0.919), conversion rates (OR 0.748 (0.329-1.515), p = 0.412; OR 1.025 (0.537-1.954), p = 0.940), pre-emptive conversion (OR 1.994 (0.198-20.032), p = 0.552; OR 0.659 (0.145-2.991), p = 0.583), intraoperative blood loss (beta coefficient 21.19 (- 25.87-68.25), p = 0.368; beta coefficient - 12.34 (- 56.13-31.44), p = 0.573), intraoperative transfusion (OR 1.962 (0.813-4.735), p = 0.127; OR 0.670 (0.260-1.727), p = 0.397), and rates of unusual bleeding (OR 1.273 (0.698-2.321), p = 0.422; OR 0.572 (0.290-1.126), p = 0.099). Time to preemptive conversion was shorter when procedures were performed by consultants (beta coefficient - 25.51 (- 47.71 to - 3.31), p = 0.025), while no difference was found for the teaching group (beta coefficient 4.48 (- 30.95-40.62), p = 0.788).

conclusionWithin a standardized teaching environment, colonic resections were safely performed regardless of the surgical setting in the present cohort. Teaching does not increase intraoperative adverse events.
