No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.

What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Objective: Obesity is associated with functional alterations in the hypothalamic–pituitary–thyroid (HPT) axis. Although bariatricsurgery induces substantial weight loss and metabolic improvement, postoperative thyroid hormone changes and potential differencesbetween surgical procedures remain unclear.Patients and Methods: This retrospective cohort study included 165 patients with obesity who underwent sleeve gastrectomy (SG,n=133) or Roux-en-Y gastric bypass (RYGB, n=32) between 2016 and 2020. Patients receiving thyroid-related treatment were excluded.Anthropometric, metabolic, and thyroid function parameters were assessed at baseline and 12 months postoperatively. Within-groupand between-procedure changes were analyzed using nonparametric tests. Associations between hormonal and metabolic changeswere evaluated using Spearman’s rank analysis.Results: At baseline, 99.4% were euthyroid. At 12 months, significant reductions occurred in body weight, body mass index (BMI), fastingglucose, glycated hemoglobin (HbA1c), insulin, thyroid-stimulating hormone (TSH), free thyroxine (fT4), and free triiodothyronine(fT3) (all p
