Association of Metabolic Score for Insulin Resistance with Intraoperative QTc Interval Changes During Laparoscopic Sleeve Gastrectomy: A Prospective Observational Study.
Observational study in Obesity surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPreoperative metabolic status may influence cardiac repolarization under anesthesia. This study investigated the relationship between the Metabolic Score for Insulin Resistance (METS-IR) and intraoperative QTc dynamics during laparoscopic sleeve gastrectomy (LSG).
methodsThis prospective observational study included 75 patients with severe obesity (body mass index ≥ 40 kg/m²) undergoing LSG. Preoperative METS-IR was calculated from laboratory data. The QT interval, Fridericia-corrected QT interval (QTcF), Tp-e interval, and Tp-e/QT ratio were recorded at baseline (T
resultsThe METS-IR-ΔQTcF association was most evident at T
conclusionIn this exploratory cohort of hemodynamically stable patients undergoing uncomplicated LSG, METS-IR was associated with QTcF dynamics, particularly at T
