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

introductionObesity and its associated comorbidities represent a pervasive problem in the United States across all age groups. There are conflicting data regarding the effectiveness and postoperative recovery of bariatric surgery in elderly patients. The aim of this study was to compare outcomes of bariatric surgery across age groups. MATERIALS AND

methodsAfter obtaining institutional review board approval, patients with morbid obesity who underwent non-revisional laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG) at our institution between 2011 and 2015 were included in this retrospective study. Patients were subdivided into five age groups: < 30, 30-39, 40-49, 50-59, and ≥ 60 years. Patient baseline demographics and comorbidities were collected. Postoperative outcomes including reinterventions/reoperations, 30-day-readmissions, 90-day-mortality, comorbidities' resolution, and change in BMI (ΔBMI) up to 4 years were recorded and compared. The groups were compared with ANOVA and chi-square tests and multivariable analyses.

resultsLRYGB was performed in 74.7% of the 1026 study patients. Patients ≥ 60 years old demonstrated lower preoperative BMI than patients < 50 years (p < 0.001). Patients 50-59 years old had increased length of stay compared to 30-39 (p = 0.003) and a higher prevalence of all comorbidities was found in older patients (p < 0.001). There was no significant difference in 30-day-readmissions; 90-day-mortality; reoperations; and reinterventions among the study groups. The ΔBMI was higher in younger patients and comorbidity resolution was more likely in younger patients with the exception of obstructive sleep apnea.

conclusionBariatric surgery can be accomplished safely across all age groups with satisfiable postoperative weight loss. However, older age had higher hospital stay and convalescence and lower comorbidity resolution compared to younger patients. Thus, bariatric surgery should be offered earlier in life to allow the patients to reap its benefits.
