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

introductionThe psychosocial background of subjects with severe obesity developed from childhood onset obesity (CO) and their outcomes after bariatric surgery have not been fully investigated.

methods305 subjects were enrolled in the J-SMART study, which examined the effects of laparoscopic sleeve gastrectomy (LSG) in Japan, and categorized into two groups: CO defined as onset up to 13 years of age (CO group) and post-puberty onset obesity defined as onset after 13 years of age (PPO group). The subjects were followed up for at least 2 years and up to 5 years after LSG. Changes in physical parameters and remission of obesity-related comorbidities were assessed at 2 years after LSG. Weight regain (WR) was also assessed by evaluating the nadir weight after LSG and maximum weight thereafter during follow-up period.

resultsThe mean postoperative follow-up period was 3.0 ± 1.1 years. 40.0% of the subjects had CO and these subjects had higher BMI and HOMA-β and lower age, HbA1c, HDL cholesterol, and visceral/subcutaneous fat area ratio compared to those with PPO. The CO group was also characterized by having higher rates of mental retardation, developmental disorders, and obesity in either parent and lower rate of marriage compared to the PPO group. Two years after LSG, there were no differences in total weight loss and remission rates of diabetes, dyslipidemia, and sleep apnea syndrome between the two groups, although remission rate of hypertension was higher in the CO group. The CO group also had a higher rate of WR after LSG than the PPO group, with CO, BMI, mental disorder, and binge eating contributing to WR.

conclusionThis study suggests that CO might be associated with genetic and psychosocial factors. CO and PPO probably differ in pathogenesis and may require different treatment strategies.
