Bariatric Surgery Outcomes in an Italian Single-Center Study: Does Chronotype Matter?
Article in Obesity surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundChronotype reflects an individual's intrinsic circadian preference for the timing of daily behaviors, including sleep, eating, and physical activity. It influences not only biological rhythms but also lifestyle patterns that may impact metabolic health. In the context of bariatric surgery, numerous factors may affect postoperative outcomes such as weight loss and the risk of weight regain. Given the growing interest in chronobiology and its relevance to obesity management, this study aimed to explore whether chronotype is significantly associated with key weight loss outcomes following bariatric surgery at 6 and 12 months post-intervention.
methodsA total of 263 patients underwent bariatric surgery at a single center. Baseline assessments included anthropometric, biochemical, and behavioral evaluations, including chronotype categorization. Postoperative outcomes at 6 and 12 months included absolute weight, BMI, percentage of initial body weight loss (%IBWL), and percentage of excess body weight loss (%EBWL).
resultsThere was no significant difference among the three different chronotypes (evening, intermediate, and morning chronotype) in terms of absolute weight, BMI, %EWL and %IBWL at 6 and 12 months after surgery.
conclusionsOur results suggest that chronotype does not seem to play a critical role in weight loss outcomes in bariatric surgery patients, characterized by severe obesity. Further studies are needed to more thoroughly assess the impact of chronotype on bariatric surgery outcomes and a more detailed characterization of chronotype itself in these patients could be decisive.
