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

backgroundSome patients with uncomplicated diverticulitis have extraluminal air. Our objective was to determine if patients with Hinchey 1a diverticulitis and isolated extraluminal air present more severe episode than patients without extraluminal air.

methodsThe present study is a monocentric observational retrospective cohort study. Computed tomographies of patients with diagnosed uncomplicated diverticulitis were retrospectively reviewed from the 01 January 2005 to the 31 December 2009. The presence of extraluminal air was determined. Leukocyte count, CRP value, and length of hospitalization were extracted from the patients' files. The follow-up period was from the time of diagnosis to the 15th of March 2019, the latest. Follow-up was censored for death and sigmoidectomy. Recurrence and emergency sigmoidectomy were documented during the follow-up period. The study was performed according to the STROBE guideline.

resultsThree hundred and one patients with an episode of Hinchey 1a diverticulitis were included. Extraluminal air was present in 56 patients (18.60%). Leukocyte count (12.4 ± 4.1(G/l) versus 10.7 ± 3.5(G/l), p = 0.05), CRP value (156.9 ± 95.1(mg/l) versus 89.9 ± 74.8(mg/l), p < 0.001), and length of hospital stay (10.9 ± 5.5(days) versus 8.4 ± 3.6(days), p < 0.001) were significantly higher in patients with extraluminal air than in patients without extraluminal air. Seventy-two patients (23.92%) presented a recurrence during the follow-up period. Survival estimates did not differ between patients with or without extraluminal air (p = 0.717). Eleven patients (3.65%) required emergency surgery during the follow-up period. Patients with extraluminal air had shorter emergency surgery-free survival than patients without extraluminal air (p < 0.05).

conclusionThe presence of extraluminal air in Hinchey 1a diverticulitis indicates a more severe episode, with higher inflammation parameters at admission, longer length of stay, and an increased risk for emergency sigmoidectomy.
