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

objectiveData are sparse regarding the survival benefit of bariatric surgery on mortality among persons with diabetes. We aimed to investigate the association of bariatric surgery, compared with usual care, on all-cause mortality in individuals who underwent surgery and matched controls, stratified by the presence of diabetes. RESEARCH DESIGN AND

methodsThis retrospective cohort study utilized population-based electronic medical record data. Individuals who underwent one of three types of bariatric surgery during 2005-2014 were included. For each surgical patient, three non-surgical individuals were matched according to age, sex, body mass index, and diabetes status. The cohort comprised 9564 individuals with diabetes and 23,976 individuals without diabetes.

resultsDuring a median follow-up of 4.2 years, adjusted hazard ratios (HRs) for mortality for non-surgery vs. surgery were 2.38 (95%CI: 1.75, 3.26) and 1.73 (95%CI: 1.26, 2.36) among individuals with diabetes and individuals without diabetes, respectively. Considered separately, HRs for mortality for laparoscopic banding, gastric bypass, and laparoscopic sleeve gastrectomy were 2.83 (95%CI: 1.73, 4.63), 2.30 (95%CI: 1.25, 4.25), and 1.89 (95%CI: 1.1, 3.32) among patients with diabetes; and 1.74 (95%CI: 1.20, 2.52), 2.66 (0.81, 8.76), and 1.16 (0.51, 2.65) among patients without diabetes.

conclusionThe survival advantage of bariatric surgery after a median follow-up of 4.2 years was greater among individuals with than without diabetes for the three types of surgery performed. Longer follow-up is needed to examine the effect on survival in individuals without diabetes who undergo bariatric surgery. These results suggest priority considerations for bariatric surgery candidates.
