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

backgroundRecent studies have shown that hospital type impacts patient outcomes, but no studies have examined hospital differences in outcomes for patients undergoing minimally invasive surgery (MIS) for segmental colectomies.

methodsThe 2010-2014 National Cancer Data Base was queried for patients undergoing segmental colectomy for non-metastatic colon adenocarcinoma. Descriptive statistics characterized MIS utilization by hospital type. Multivariable models were used to examine the effect of hospital type on outcomes after MIS. Survival probability was plotted using the Kaplan-Meier method.

results80,922 patients underwent MIS segmental colectomy for colon cancer from 2010 to 2014. From 2010 to 2014, the number of MIS segmental colectomies increased by 157% at academic hospitals, 151% at comprehensive hospitals, and 153% at community hospitals. Compared to academic hospitals, community and comprehensive hospitals had greater adjusted odds of positive margins (Community OR 1.525, 95% Confidence Interval 1.233-1.885; Comprehensive OR 1.216, 95% CI 1.041-1.42), incomplete number of lymph nodes analyzed (< 12 LNs) from surgery (Community OR 2.15, 95% CI 1.98-2.32; Comprehensive OR 1.42, 95% CI 1.34-1.51), and greater 30-day mortality (Community OR 1.43, 95% CI 1.14-1.78; Comprehensive OR 1.36, 95% CI 1.17-1.59). Patient survival probability was higher at academic hospitals at 5 years (Academic 69% vs. Comprehensive 66% vs. Community 63%, p < 0.001). Community hospitals and comprehensive hospitals had significantly higher risk of adjusted long-term mortality (Community HR 1.28; 95% CI 1.19-1.37; p < 0.001; Comprehensive HR 1.14; 95% CI 1.09-1.20; p < 0.001).

conclusionsDespite widespread use of laparoscopic oncologic surgery, short- and long-term outcomes from MIS for segmental colectomy are superior at academic hospitals. This difference may be due to superior perioperative oncologic technique and surgical outcomes at academic hospitals. Our data provide important information for patients, referring physicians, and surgeons about the significance of hospital type in management of colon cancer.
