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

importanceCigarette smoking increases the risk of surgery in Crohn's disease. However, the effect of smoking on the need for surgery for diverticulitis is unknown.

objectiveWe evaluated whether smoking was a risk factor for surgery among patients admitted to hospital with acute diverticulitis.

designWe conducted a population-based comparative cohort study of patients admitted to hospital for diverticulitis who were treated with medical versus surgical management. SETTING &

participantsWe used the population-based Discharge Abstract Database to identify 176 adults admitted emergently with a diagnosis of diverticulitis between 2009 and 2010 in Calgary. INTERVENTION & MAIN OUTCOME: We performed a medical chart review to confirm the diagnosis of diverticulitis and to extract clinical data. The primary outcome was a partial colectomy during hospitalization. Logistic regression evaluated the association between smoking and surgery after adjusting for potential confounders, including age, sex, comorbidity, and disease severity.

resultsA partial colectomy was performed on 35.6% of patients with diverticulitis and 1.3% died. Among diverticulitis patients, 26.8% were current smokers, 31.5% were ex-smokers, and 41.6% never smoked. Compared to non-smokers, current smokers (adjusted odds ratio [OR] 9.02; 95% confidence interval [CI]: 2.47-32.97) and former smokers (adjusted OR 5.41; 95% CI: 1.54-18.96) had increased odds of surgery. CONCLUSION AND RELEVANCE: Smoking is associated with the need for surgical management of diverticulitis.
