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

backgroundTo provide greater insight into bariatric surgery outcomes in aging patients, we compared changes in body weight, body composition, obesity-related comorbidities, and nutritional status between older and younger subjects.

methodsWe analyzed data collected between January 2004 and December 2014 from our prospective bariatric cohort. Older patients (OP, ≥ 60 years at the time of surgery, n = 93; 66% Roux-en-Y gastric bypass, 34% sleeve gastrectomy) were compared with younger patients (YP, < 60 years, n = 186), matched 1:2 on sex, body mass index, diabetes, and surgical procedure. Body composition was assessed by dual-energy X-ray absorptiometry.

resultsWeight loss and excess weight loss at 12 months were lower in OP vs. YP (mean ± SD, 30.1 ± 10.1 vs. 34.1 ± 11.9 kg, 60.6 ± 21.2 vs. 66.8 ± 23.4%, respectively, p < 0.05 for both). Both lean body mass and fat mass loss were lower in OP vs. YP (8.4 ± 3.4 vs. 9.2 ± 9.0 kg, 19.4 ± 8.7 vs. 21.9 ± 9.1 kg, respectively, p < 0.05). The remission rate for type 2 diabetes was significantly lower in OP vs. YP (24 vs. 45%), as well as improvement in hypertension (14 vs. 46%), dyslipidemia (27 vs. 47%), and knee pain. There was no difference in micronutrient deficiencies between groups.

conclusionsThese data indicate that although bariatric surgery is not as effective for weight loss in older as in younger subjects, it is a safe option regarding a comprehensive set of nutritional variables which enables significant improvement in obesity-related outcomes.
