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

backgroundPrevious work from our institution has characterized the learning curve for open ileal pouch-anal anastomosis (IPAA). The purpose of the present study was to assess the learning curve of minimally invasive IPAA.

methodsPerioperative outcomes of 372 minimally invasive IPAA by 20 surgeons (10 high-volume vs. 10 low-volume surgeons) during 2002-2013, included in a prospectively maintained database, were assessed. Predicted outcome models were constructed using perioperative variables selected by stepwise logistic regression, using Akaike's information criterion. Cumulative sums (CUSUM) of differences between observed and predicted outcomes were graphed over time to identify possible improvement patterns.

resultsInstitutional pelvic sepsis and other pouch morbidity rates (hemorrhage, anastomotic separation, pouch failure, fistula) significantly decreased (18.2 vs. 7.0 %, CUSUM peak after 143 cases, p = 0.001; 18.4 vs. 5.3 %, CUSUM peak after 239 cases, respectively, p < 0.001). Institutional total proctocolectomy mean operative times significantly decreased (307 min vs. 253 min, CUSUM peak after 84 cases, p < 0.001), unlike completion proctectomy (p = 0.093) or conversion rates (10 vs. 5.4 %, p = 0.235). Similar learning curves were identified among high-volume surgeons but not among low-volume surgeons. Learning curves were identified in the two busiest individual surgeons for pelvic sepsis (peaks at 47 and 9 cases, p = 0.045 and p = 0.002) and in one surgeon for operative times (CUSUM peak after 16 and 13 cases for both total proctocolectomy and completion proctectomy (p < 0.001 and p = 0.006) but not for other pouch complications (peak at 49 and 41 cases, p = 0.199 and p = 0.094).

conclusionPouch complications, particularly pelvic sepsis, are the most consistent and relevant learning curve end points in laparoscopic IPAA.
