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

backgroundThe elderly population in the United States is projected to double by 2050, along with obesity prevalence. Despite the increasing number of elderly patients undergoing bariatric surgery, evidence on perioperative safety remains limited and conflicting. Given concerns about higher perioperative morbidity, we compared 30-day outcomes and bariatric-specific complications after Roux-en-Y gastric bypass (RYGB) across age subgroups within the elderly bariatric population.

methodsPatients aged > 60 years who underwent RYGB were identified from the 2015 to 2023 MBSAQIP database. A 1:1 propensity score matching analysis using 22 preoperative characteristics was performed to compare 30-day outcomes between early versus late sexagenarians (60-64 vs. 65-69), early versus late septuagenarians (70-74 vs. 75-79), and late sexagenarians versus early septuagenarians (65-69 vs. 70-74).

resultsWe analyzed 45,775 RYGB patients. Except for Analysis 1, no differences were found in mortality, unplanned ICU admissions, or cardiopulmonary complications. After matching, Analysis 1 (n = 16,273) showed that late sexagenarians had higher rates of mortality, pulmonary complications, unplanned ICU admissions, blood transfusions, readmissions, and non-home discharge. In Analysis 2 (n = 2351; n = 600), late septuagenarians had higher rates of pulmonary complications, conversion to open, and non-home discharge. In Analysis 3 (n = 4307), early septuagenarians had higher rates of venous thromboembolism and non-home discharge.

conclusionsRYGB is safe and feasible across elderly subgroups, with acceptable mortality, unplanned ICU admission, and cardiopulmonary complication rates. However, patients aged > 65 had significantly higher mortality and morbidity, suggesting this age as a threshold for increased perioperative risk. These findings highlight the importance of careful patient selection and preoperative optimization, particularly in patients older than 65 years.
