Immediate improvement in anxiety and sleep quality with delayed depression response after bariatric surgery in a longitudinal cohort study.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Obesity demonstrates bidirectional associations with anxiety, depression and sleep quality. Although bariatric surgery effectively alleviates obesity-related mental health issues, the mechanisms and temporal dynamics of mental symptom improvements remain unclear. This longitudinal study aims to explore the time points at which mental health and sleep quality change after bariatric surgery in overweight/obese patients, and explore correlation between anxiety, depression and sleep quality. Seventy-eight overweight/obese patients (OW/OB) who underwent Laparoscopic sleeve gastrectomy at the Bariatric Center of Shanghai Sixth People's Hospital were included by cohort. Sixty-five healthy controls (HC) were matched by age and sex. Patients received Chinese versions of the Beck Depression Inventory II (BDI), Beck Anxiety Inventory (BAI), and Pittsburgh Sleep Quality Index (PSQI) completed during monthly follow-up surveys after surgery. Before surgery, the OW/OB group had significantly worse anxiety, depression, and sleep problems than HC (all p < 0.001). After surgery, BAI and PSQI scores decreased significantly at all time points, and BDI scores began to decrease at 1 year postoperatively compared with baseline (all p < 0.05). There was a stable positive correlation between preoperative body mass index, BAI, BDI, and PSQI scores, which broke down in the postoperative period. Bariatric surgery improved anxiety symptoms and sleep quality in overweight or obese patients, while depressive symptoms showed delayed but statistically significant improvements at later follow-up points. Stable associations between anxiety, depression, and sleep quality in overweight or obese patients may require multiple interventions.
