Bariatric Surgeries, from Weight Loss to Weight Regain: A Retrospective Five-Years Cohort Study.

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
introductionBariatric surgery may lead to unsatisfactory weight loss, weight loss plateau, and even weight regain after various types of surgery. Despite the numerous studies, the mid-term results of surgery, after repetitive weight fluctuations remain a major concern. The aim of the present study was to determine the key time points of weight changes after three types of bariatric procedures, as well as to determine 5-year weight loss outcome after surgery.
methodsThis is a retrospective cohort study including patients with morbid obesity conducted in the Minimally Invasive Surgery Research Center. The patients underwent one of the three types of bariatric surgeries including laparoscopic sleeve gastrectomy (LSG), Roux-en-Y gastric bypass (RYGB), and one-anastomosis gastric bypass (OAGB), who had been followed up for weight loss trend during 5 years postoperatively.
resultsThe mean excessive weight loss (%EWL) and total weight loss (%TWL) of 2,567 participants with obesity (mean age = 39.03, mean BMI = 45.67) in the first 6 months after surgery was independent of the type of surgery (p > 0.05). OAGB and RYGB showed significantly higher weight loss compared to LSG in ninth and 24th month after surgery, respectively (p < 0.05). The 5 years %WL could be comparable with %WL in 6, 9, and 12 months after LSG, RYGB, and OAGB, respectively.
conclusionOAGB provides the fastest and highest %EWL and %TWL, while LSG induced the earliest and largest weight plateau and weight regain during 5-years post-surgery. The pattern of early weight loss could predict the mid-term outcome of bariatric surgery. So, early identification of suboptimal weight loss could enhance long-term weight loss.
