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

importanceMinimally invasive colectomy (MIC) is an increasingly common surgical procedure. Although case series and controlled prospective trials have found the procedure to be safe, it is unclear whether safe adaptation of this approach from open colectomy (OC) is occurring among surgeons.

objectiveTo assess rates of complications for MIC compared with OC among surgeons. DESIGN, SETTING, AND

participantsWe analyzed 5196 patients who underwent MIC or OC from January 1, 2012, through December 31, 2015, by 97 surgeons in the Michigan Surgical Quality Collaborative, with each surgeon performing at least 10 OCs and 10 MICs. Hierarchical regression was used to assess surgeon variation in adjusted rates of complications and the association of these outcomes across approaches. MAIN OUTCOMES AND MEASURES: Primary study outcome measurements included overall 30-day complication rates, variation in complication rates among surgeons, and surgeon rank by complication rate for MIC vs OC.

resultsOf the 5196 patients (mean [SD] age, 62.9 [14.4] years; 2842 [54.7%] female; 4429 [85.2%] white), 3118 (60.0%) underwent MIC and 2078 (40.0%) underwent OC. Overall, 1149 patients (22.1%) experienced complications (702 [33.8%] in the OC group vs 447 [14.3%] in the MIC group; P < .001). For MIC, the rates of complications varied from 8.8% to 25.9% among surgeons. For OC, rates of complications were higher but varied less (1.7-fold) among surgeons, ranging from 25.9% to 43.8%. Among the 97 surgeons ranked, the mean change in ranking between OC and MIC was 25 positions. The top 10 surgeons ranged in rank from 6 of 97 for OC to 89 of 97 for MIC. CONCLUSIONS AND RELEVANCE: Surgeon-level variation in complications was nearly twice as great for MIC than for OC among surgeons enrolled in a statewide quality collaborative. Moreover, surgeon rankings for OC outcomes differed substantially from outcomes for those same surgeons performing MIC. This finding implies a need for improved training in adoption of MIC techniques among some surgeons.
