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

backgroundAlthough bariatric surgery is an effective treatment for obesity, utilization of bariatric procedures in older adults remains low. Previous work reported higher morbidity in older patients undergoing bariatric surgery. However, the generalizability of these data to contemporary septuagenarians is unclear.

objectivesWe sought to evaluate differences in 30-day outcomes, 1-year weight loss, and co-morbidity remission after bariatric surgery among 3 age groups as follows: <45 years, 45-69 years, and ≥70 years.

settingStatewide quality improvement collaborative.

methodsUsing a large quality improvement collaborative, we identified patients undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) between 2006 and 2018. We used multivariable logistic regression models to evaluate the association between age cohorts and 30-day outcomes, 1-year weight loss, and co-morbidity remission.

resultsWe identified 641 septuagenarians who underwent SG (68.5%) or RYGB (31.5%). Compared with 45-69 year olds, septuagenarians had higher rates of hemorrhage (5.1% versus 3.1%; P = .045) after RYGB and higher rates of leak/perforation (.9% versus .3%; P = .044) after SG. Compared with younger patients, septuagenarians lost less of their excess weight, losing 64.8% after RYGB and 53.8% after SG. Remission rates for diabetes and obstructive sleep were similar for patients aged ≥70 years and 45-69 years.

conclusionsBariatric surgery in septuagenarians results in substantial weight loss and co-morbidity remission with an acceptable safety profile. Surgeons with self-imposed age limits should consider broadening their selection criteria to include patients ≥70 years old.
