1 · What the graph read from it

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.

2 · The registry

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

backgroundGeneral anesthesia administration in obese patients presents significant challenges. In addition to the complexity of dosage and parameter management, delayed recovery from anesthesia substantially increases the risk of postoperative complications. Thus, promoting rapid recovery in this population is crucial. However, factors associated with delayed recovery in obese patients remain poorly understood. Given the influence of metabolism on brain activity and connectivity, this exploratory study aimed to identify metabolic factors associated with delayed recovery in obese individuals.

methodsThis study included 102 obese patients undergoing minor or moderate surgery under total intravenous anesthesia, with depth of anesthesia guided by the bispectral index. Peripheral circulating levels of leptin, orexin A, adiponectin, and lipid profiles were measured. Emergence time was defined as the duration from discontinuation of anesthetics to eye opening on command.

resultsThe median emergence time was 8 min (IQR 6-12). Univariate analysis indicated that patient height, sex, and leptin concentration were correlated with emergence time. Multivariate analysis revealed that circulating leptin was an independent factor associated with emergence time (β = -0.91, 95% CI: -1.42 to - 0.39, adjusted R² of 0.18).

conclusionsCirculating leptin level is associated with emergence time from general anesthesia in obese patients. However, it explains only a limited portion of the variability in emergence time given the low R
