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

aimsPostoperative delirium (PD) is a common and severe complication in older adult patients undergoing invasive cancer resections. This study explored the plasma metabolome associated with PD and evaluated the efficacy of Yokukansan (YKS), a traditional Japanese Kampo medicine, in preventing PD.

methodsAn ancillary study was conducted alongside a double-blind, placebo-controlled randomized clinical trial involving patients 65 years and older, focusing on patients older than 75 years as a primary analysis population. Plasma samples were analyzed using targeted and nontargeted metabolomics. An in vivo study using aged mice assessed the effects of YKS on plasma and brain metabolites.

resultsA total of 83 patients, including 21 patients older than 75 years, were enrolled. Patients with PD had lower levels of several lipid mediators, free fatty acids, and phospholipids. YKS administration led to increased nine phospholipids and four hydrophilic metabolites in patients older than 75 years, including phosphatidylcholine (40:7) and phosphatidylcholine (42:8), which were also altered in delirium patients. In the patients older than 65 years, only two metabolites increased in the YKS administration group. In aged mice, YKS elevated plasma phospholipids, similar to findings in patients older than 75 years, and influenced brain citrulline and creatine, which related to oxidative stress and cognitive function. Correlation analyses revealed associations between plasma and brain metabolite changes.

conclusionOur findings suggest that the plasma metabolome provides insight into the pathophysiology of PD and the potential mechanism underlying the preventive effect of YKS against PD.
