Relationship between psychiatric disorders and loss weight among patients underwent metabolic and bariatric surgery: A reassessment observational study after nine years.
Observational study in Clinics (Sao Paulo, Brazil), 2024. 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
objectiveTo evaluate the evolution of Psychiatric Disorders (PD) and weight loss at different postoperative intervals up to 9 years after Metabolic and Bariatric Surgery (MBS).
methodsThis is a nine-year longitudinal study conducted at a single university-based bariatric center in Brazil. The Generalized Estimating Equation (GEE) and multiple linear regression models were used to evaluate the proportion of lifetime PD according to TPS, and its relationship with weight. The Structured Clinical Interview for DSM-5 assessed the PD and the percentage of Excess Lost Weight (%EWL) for weight changes. The study included 142 participants who had undergone MBS, mostly women (82 %), mean age of 52 years.
resultsDepression and anxiety disorders were the most common PD. Regardless of the time elapsed since MBS, there was an increase of 32 % in lifetime mood disorders, bipolar disorders, and eating disorders. The average EWL for Time Post-Surgery (TPS) ≤ 24 months was 69 % and remained consistent until 72 months; after was 57 % and 58 % for ≤ 72 and 96 months, respectively. There was not a significant association between %EWL and PD when controlling for sex, age, and time post-surgery.
conclusionPsychiatric disorders can be associated and remain prevalent, regardless of time post-surgery; however, this does not significantly impact weight losss maintenance. It is recommended that individuals who have undergone MBS be monitored and supported over an extended period to address psychiatric comorbidities.
