Association of preoperative frailty with suboptimal weight loss response among patients undergoing metabolic and bariatric surgery.

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
backgroundPreoperative patient frailty (i.e., aging-related functional decline across multiple physiological systems) has been linked to greater perioperative complications following metabolic bariatric surgery (MBS). This study evaluated whether preoperative patient frailty predicts 1-year suboptimal weight loss response after primary sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB).
methodsThe Bariatric Frailty Score (BFS), an adapted version of the Canadian Study of Health and Aging-Frailty Index based on 10 variables from MBSAQIP, assessed degree of frailty based on number of deficits (i.e., 0-10). Suboptimal response to MBS was defined as < 20% and < 30% percentage total weight loss (%TWL) at 1 year following SG and RYGB, respectively. Multiple linear and logistic regression models evaluated associations of preoperative BFS score with %TWL and %TWL response thresholds, respectively.
resultsPatients (n = 1574; 78.9% female, 28.3% non-white, mean age 45 ± 12 year; 67% SG) had a mean BFS of 1.6 ± 1.3 (range = 0-7). Overall, higher BFS related to lower %TWL after SG and RYGB (ß = - 0.12 and ß = - 0.17, respectively, p = 0.001). Compared to patients with 0-1 deficits (BFS score ≤ 1; n = 785, 49.9%), those with multiple deficits (BFS score ≥ 2; n = 789, 50.1%) had higher odds of suboptimal weight loss response after SG (OR 1.88, 95% CI 1.40-2.52, p < 0.001) and RYGB (OR 2.18, 95% CI 1.43-3.32, p < 0.001).
conclusionHaving multiple preoperative frailty deficits is associated with higher odds of suboptimal weight loss response after MBS. These findings point to the need for increased frailty screening and appropriate adjunctive interventions (i.e., exercise, nutrition, and cognitive), as these interventions may improve frailty status and MBS outcomes.
