Prolonged sedentary time adversely relates to physical activity and obesity among preoperative bariatric surgery patients.

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
backgroundBariatric surgery patients spend much of their waking time sedentary. Yet, little is known about their patterns of accumulation of sedentary time (ST) and whether more prolonged ST is associated with lower physical activity (PA), independent of total ST, or obesity severity.
objectivesTo characterize variability in prolonged ST among bariatric patients preoperatively and assess the importance of a "prolonger" pattern in relation to PA and weight status.
settingTwo university hospital clinics, United States.
methodsAdult patients (n = 76) wore a wrist-based accelerometer for 10 days preoperatively. ST and time spent in light and moderate-to-vigorous PA was determined using validated thresholds. Percent of total ST accumulated in ≥30-consecutive ST minute bouts was calculated, and participants were trichotomized into low, medium, and high "prolongers" based on this value. The associations of prolonged ST with PA and obesity were examined.
resultsOn average, participants accumulated a mean ± standard deviation of 10.5 ± 2.1 hours of ST per day, 30% of which was prolonged (prolonger groups: low = 7.2%-24.5%, medium = 24.5%-33.0%, and high = 34.0%-52.6% of ST in ≥30-min bouts). Adjusting for covariates including total ST, high prolongers had fewer light PA minutes per day (P < .01), and a greater percentage of prolonged ST related to lower likelihood of meeting the national guideline of ≥150 moderate-to-vigorous PA minutes per week (P = .012). High (versus low) prolongers had more severe obesity (P < .05).
conclusionsAccumulating a greater percentage of ST in prolonged bouts appears to be adversely related to PA and obesity severity among bariatric patients. Future research should determine whether interrupting prolonged ST with brief breaks can favorably modify PA and weight in this population.
