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

backgroundComplications after rectal resection are frequent. Recently, methods to assess visceral obesity (VO) have become available as an alternative to measurement of body mass index (BMI). The aim of this study was to examine the association between visceral fat volume (VFV) and the short-term outcomes after laparoscopic low anterior resection (LLAR) in patients with rectal cancer.

methodsWe studied a consecutive series of patients undergoing LLAR at Bispebjerg University Hospital from 01.01.2013 to 01.01.2016. Preoperative VFV was calculated from abdominal CT scans using an automatic segmentation tool. The primary outcome was anastomotic leakage (AL). Secondary outcomes included conversion to open surgery, number of lymph nodes harvested, the rates of 30-day complications as well as reoperations, and 1-year survival.

resultsA total of 102 patients were included. VO was defined as a VFV above the 75 percentile. Thirteen (12.7%) patients developed AL, four (15.4%) of whom were in the VO group (p = 0.900). At least one postoperative complication developed in 38 (37.3%) patients, with no significant difference between the VO and non-VO patients after univariable analysis (42.3% vs. 35.4%, p = 0.702) or multivariable adjustment (OR 1.01, 95% CI 0.38-2.65, p = 0.984). VO was significantly associated with an increased incidence of conversion to open surgery (OR 4.30, 95% CI 1.29-14.86, p = 0.018). There was a significant difference in the number of harvested lymph nodes between the two groups (mean 23.5 vs. 29.1, p = 0.045).

conclusionsIn this study on patients undergoing laparoscopic rectal resection, VO was not associated with development of AL or other complications. However, we found that visceral obesity was associated with an increased risk of conversion to open surgery.
