Impact of age on morbidity and mortality following bariatric surgery.
Article in Surgical endoscopy, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
backgroundBariatric surgery is the most effective modality to treat obesity and obesity-related comorbidities. This study sought to utilize the MBASQIP® Data Registry to analyze the impact of age at time of surgery on outcomes following sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) procedures.
methodsThe MBSAQIP® Data Registry for patients undergoing SG or RYGB procedures between 2015 and 2016 was reviewed. Patients were divided into 4 age groups [18-44; 45-54; 55-64; > 65 years]. Minimal exclusions for revisional and/or emergency surgery were selected and combination variables created to classify complications as major or minor. A comorbidity index was constructed to include diabetes, gastroesophageal reflux disease (GERD), obstructive sleep apnea (OSA), and prior cardiac surgery. Univariate and multivariate logistic regression analyses were performed to compare age stratifications to the young adult (18-45 years) cohort.
resultsOf 301,605 cases, 279,419 cases (71.2% SG) remained after applying exclusion criteria (79.2% female, mean BMI 45.5 ± 8.1 kg/m
conclusionOverall, bariatric surgery (SG or RYGB) remains a low mortality risk procedure for all age groups. However, all age group classifications > 45 years had higher incidence of major complications and mortality compared to patients 18-45 years (despite older individuals having lower preoperative BMI) indicating delaying surgery is detrimental.
