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

backgroundThis study evaluated the outcomes of colonic volvulus management in a national cohort, and identified risk factors for morbidity and mortality.

methodsThis was a multicentre national retrospective study of patients presenting with colonic volvulus between 2010 and 2019. Main outcome measures were 30-day and 1-year mortality. Multivariable regression and Kaplan-Meier analyses were used to study predictors of mortality and survival.

resultsOf the 559 patients presenting with sigmoid volvulus, 381 underwent surgery and 178 received conservative treatment. The 30-day mortality rates were 11.0% and 19.0%, respectively. Emergency surgery (P = 0.030), nursing home residence (P = 0.040), increased co-morbidity (P = 0.017), and male sex (P = 0.029) predicted postoperative 30-day mortality. Primary endoscopic detorsion followed by elective surgery during a subsequent hospital admission resulted in best survival. Of the 342 patients presenting with caecal volvulus, 340 underwent surgery. The 30-day mortality rate was 6.4%. Increased co-morbidity (P = 0.008), nursing home residence (P = 0.002), and necrotic caecum (P = 0.007) predicted 30-day mortality. At 1 year, the mortality rate among patients with sigmoid volvulus was 19.9% after surgery and 43.2% after conservative treatment. Emergency surgery (P = 0.023), nursing home residence (P = 0.009), and increased co-morbidity (P < 0.001) were associated with 1-year postoperative mortality. In patients with caecal volvulus the 1-year mortality rate was 13.1%. Increased co-morbidity (P < 0.001) and nursing home residence (P < 0.001) were predictive. Anastomotic leakage in patients with sigmoid volvulus was associated with an American Society of Anesthesiologists fitness grade of III (P = 0.032) and total colectomy (P = 0.012).

conclusionSurgery should be recommended for colonic volvulus where co-morbidity, patient preference, and functional status allows. Surgically unfit patients have poorer outcomes. Elective sigmoidectomy after endoscopic detorsion is preferred as it carries the lowest mortality risk. Necrotic bowel, dependency, and co-morbidities predict death for both sigmoid and caecal volvulus.
