Pre-surgical Weight Loss Predicts Post-surgical Weight Loss Trajectories in Adolescents Enrolled in a Bariatric Program.
Article in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
introductionAdolescent obesity is markedly increasing worldwide and bariatric surgery is emerging as an effective treatment option. However, a subset of patients fails to achieve significant weight loss or show post-surgical weight regain. Efforts have been made to identify different post-surgical weight trajectories and their possible predictors. Furthermore, the role of pre-surgical intervention programs in optimizing post-surgical results has been a subject of debate.
objectivesThis study aimed to evaluate the impact of a 3-month lifestyle-oriented pre-surgical program for adolescent candidates for bariatric surgery on pre-surgical weight loss (body mass index (BMI) on completion - BMI at admission), and to identify predictors of different post-surgical weight loss trajectories.
methodsForty-eight adolescent bariatric surgery candidates were enrolled in a lifestyle- and behavior-oriented bariatric program consisting of a 3-month pre-surgical outpatient intervention and a 6-month post-surgical follow-up.
resultsMean BMI decreased by 1.82 points (SD = 1.83) during the program's pre-surgical intervention phase, a 3.8% average drop in participants' BMI; post-surgical weight loss trajectories were significantly associated in a curvilinear model with pre-surgical weight loss; optimal post-surgical results were associated with moderate pre-surgical weight loss, and inversely associated with maternal history of obesity, early-life weight loss attempts, and comorbid learning disorders.
conclusionsModerate weight loss in a pre-surgical lifestyle-oriented intervention program predicts optimal post-surgical weight loss. Additionally, by assessing risk factors and pre-surgical weight loss patterns, it may be possible to identify sub-populations of adolescents undergoing bariatric surgery at risk of achieving sub-optimal long-term results.
