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

objectiveMinimally invasive radical hysterectomy (MIS-RH) for early-stage cervical cancer is a relatively new surgical procedure with increased utilization in the mid-/late-2000s. This study examined the association between hospital surgical volume for MIS-RH and perioperative outcomes for early-stage cervical cancer in the period of early adoption.

methodsThis population-based retrospective study queried the National Inpatient Sample from 2007 to 2011. Cervical cancer cases treated with MIS-RH were examined (n = 2202 from 163 hospitals). Annualized hospital surgical volume was defined as the average number of procedures performed per year in which at least one case was performed. Characteristics and outcomes related to MIS-RH use were assessed. The comparator cohort included RH by laparotomy (Open-RH; n = 11,187 from 405 hospitals).

resultsAmong MIS-RH-offering centers, 42.3% had average 1 case/year and surgical volume of >4 cases/year represented the top decile. When stratified by MIS-RH types, on average 31.3 centers performed robotic-assisted approach per year versus 11.5 centers for the traditional approach. Small bed capacity centers were most likely to perform robotic-assisted RH (adjusted-odds ratio 4.07, P < 0.001). In the traditional MIS-RH group, higher hospital surgical volume was associated with lower surgical morbidity (P = 0.025) whereas in the robotic-assisted approach higher hospital surgical volume was associated with higher surgical morbidity (P < 0.001). In the Open-RH cohort, higher hospital surgical volume was significantly associated with decreased surgical morbidity and mortality (both, P < 0.001).

conclusionIn the mid-/late-2000s, MIS-RH surgical volume was modest in the United States. Small bed capacity centers adopted robotic-assisted MIS-RH more frequently, and there was a statistically significant association of increased perioperative complications among higher volume centers. In contrast, higher surgical volume was associated with improved perioperative outcomes with the traditional MIS-RH and open-RH approaches.
