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

backgroundHistorically, emergency gallbladder surgery in elderly patients has been associated with high rates of morbidity and mortality. Recent studies have described much lower complication rates that may still overestimate morbidity. The purpose of this study was to determine the true population morbidity and mortality rates after gallbladder surgery in the elderly.

methodsAll elderly patients (defined as age 65 years or older) admitted to the hospital with a principle diagnosis related to benign gallbladder disease in the Province of Manitoba from January 1, 1995 to December 31, 2008 were identified by using administrative claims data. Outcomes after emergency gallbladder surgery, including complication rates and their predictors, were compared with outcomes after elective surgery and after nonoperative treatment for gallbladder-related hospital admissions.

resultsA total of 9,936 patients were included: 2,355 had emergency or urgent surgery and 4,901 had elective procedures, whereas 2,680 patients were treated without surgery. Emergency gallbladder surgery was associated with a mortality rate of 0.7 %, compared with 1.6 % for elective cases and 5.6 % for patients treated nonoperatively. Complication rates were 16.2, 17.7, and 25 % respectively. Independent predictors of 30-day mortality were age, male gender, increasing comorbidity, surgeon experience, and surgical treatment.

conclusionsEmergency gallbladder surgery in the elderly was not associated with higher mortality or complication rate compared with the elective setting. Elderly patients with gallbladder-related emergencies should be offered urgent surgery when feasible.
