Safety and Effect of Bariatric Metabolic Surgeries for Psychiatric Patients with Obesity: A Retrospective Matched Case-control Trial.
Article in Obesity surgery, 2023. 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
introductionPatients living with psychiatric illnesses (PIs) have a high prevalence of obesity. In a 2006 survey, 91.2% of professionals in the bariatric field identified "psychiatric issues" as clear contraindications to weight-loss surgery.
methodsThis retrospective matched case-control study investigated the impact, safety, and possible relapse after bariatric metabolic surgery (BMS) in patients with PIs. Also, we tested the incidence of patients who developed PI after BMS and compared the post-procedural weight loss with that in a matched control group without PIs. The cases were matched in a ratio of 1:4 to the control patients standardized for age, sex, preoperative BMI, and type of BMS.
resultsOf 5987 patients, 2.82% had a preoperative PI; postoperative de novo PI was present in 0.45%. Postoperative BMI was significantly different between the groups when compared to preoperative BMI (p < 0.001). Percentage of total weight loss (%TWL) after six months was not significantly different between the case (24.6% ± 8.9) and control groups (24.0% ± 8.4, p = 1.000). Early and late complications were not significantly different between the groups. The psychiatric drug use and dosage changes did not differ significantly pre- and postoperatively. Of the psychiatric patients, 5.1% were postoperatively admitted to a psychiatric hospital (p = 0.06) unrelated to BMS, and 3.4% had a prolonged absence from work after surgery.
conclusionBMS is an effective weight loss treatment and a safe procedure for patients with psychiatric disorders. We found no change in the patients' psychiatric status outside the usual disease course. Postoperative de novo PI was rare in the present study. Furthermore, patients with severe psychiatric illness were excluded from undergoing surgery and, therefore, from the study. Careful follow-up is necessary to guide and protect patients with PI.
