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

Postoperative cognitive dysfunction (POCD) is a common perioperative complication of the central nervous system, and patients with chronic alcohol exposure frequently require surgery under anesthesia. However, the contribution of chronic alcohol exposure to POCD and its underlying mechanisms remains unclear. In this study, eight-week-old female and male mice were subjected to chronic alcohol exposure using the intermittent access two-bottle choice (IA2BC) paradigm. Compared with controls, mice with chronic alcohol exposure exhibited greater susceptibility to POCD. Specifically, chronic alcohol exposure increased NR2B expression in hippocampal CA1 glutamatergic neurons, enhancing A/S-induced hyperexcitability, which led to neuronal apoptosis and cognitive impairment. Notably, knockdown of NR2B or chemogenetic inhibition of CA1 glutamatergic neurons in IA2BC mice could reduce neuronal apoptosis and rescue A/S-induced cognitive dysfunction. These findings demonstrate that chronic alcohol exposure heightens susceptibility to POCD in young adult mice through NR2B-mediated excitotoxicity, revealing a mechanistic link between chronic alcohol exposure and POCD that warrants further investigation.
