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

backgroundDespite strong preclinical evidence, clinical studies have reported minimal effects of early anesthesia on neurodevelopment. This discrepancy may be due to limitations of preclinical studies, including the absence of clear criteria for appropriate anesthetic depth, lack of physiological monitoring, and absence of a surgical insult. Therefore, we aimed to evaluate the effects of sevoflurane in a more clinically relevant setting by addressing these known limitations.

methodsAfter confirming robust burst suppression (BS) at 2.5% sevoflurane, postnatal day 17 (PND17) mice were assigned to three groups: a Control group, no intervention; BS (-) group, surgery with 1.4% sevoflurane; and a BS (+) group, surgery with 1.4%-2.5% sevoflurane. Total duration of anesthesia was 2 h, and blood pressure was non-invasively measured in a subset of mice. Long-term behavioral changes were evaluated from PND56 to PND62 at a two-day interval.

resultsWe found subtle but significant changes in anxiety and sociability only in BS (+) group mice. Change in anxiety level was observed in the light/dark box test, with the number of transitions between chambers significantly lower in the BS (+) group (P = 0.025). Reduced sociability was observed in the three-chamber test, as mice in the BS (+) group did not significantly prefer the chamber containing a stranger mouse (P = 0.065).

conclusionsBoth surgery and excessive anesthesia depth are necessary to induce subtle yet long-term behavioral changes in young mice. Future preclinical studies should reconsider sevoflurane concentration and account for surgical trauma as a significant factor when investigating anesthesia-induced neurotoxicity.
