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

objectiveTo perform a population-based analysis to first examine the changes in surgeon and hospital procedural volume for hysterectomy over time and then to explore the association between very low surgeon procedural volume and outcomes.

methodsAll women who underwent hysterectomy in New York State from 2000 to 2014 were examined. Surgeons were classified based on the average annual procedural volume as very low-volume surgeons if they performed one procedure per year. We used multivariable models to examine the association between very low-volume surgeon status and morbidity, mortality, transfusion, length of stay, and cost.

resultsAmong 434,125 women who underwent hysterectomy, very low-volume surgeons accounted for 3,197 (41.0%) of the surgeons performing the procedures and operated on 4,488 (1.0%) of the patients. The overall complication rates were 32.0% for patients treated by very low-volume surgeons compared with 9.9% for those treated by other surgeons (P<.001) (adjusted relative risk 1.97, 95% CI 1.86-2.09). Specifically, the rates of intraoperative (11.3% vs 3.1%), surgical site (15.1% vs 4.1%) and medical complications (19.5% vs 4.8%), and transfusion (38.5% vs 11.8%) were higher for very low-volume compared with higher volume surgeons (P<.001 for all). Patients treated by very low-volume surgeons were also more likely to have a prolonged length of stay (62.0% vs 22.0%) and excessive hospital charges (59.8% vs 24.6%) compared with higher volume surgeons (P<.001 for both). Mortality rate was 2.5% for very low-volume surgeons compared with 0.2% for higher volume surgeons (P<.001) (adjusted relative risk 2.89, 95% CI 2.32-3.61).

conclusionA substantial number of surgeons performing hysterectomy are very low-volume surgeons. Performance of hysterectomy by very low-volume surgeons is associated with increased morbidity, mortality, and resource utilization.
