Association Between the Highest Lactate Level on the First Postoperative Day and Postoperative Delirium in Cardiac Surgery Patients.
Article in CNS neuroscience & therapeutics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
aimsThe study aimed to determine the correlation between the maximum lactate on the first postoperative day and the incidence of postoperative delirium (POD) in patients after cardiac surgery.
methodsThe data of cardiac surgery patients were extracted from the Medical Information Mart for Intensive Care IV database. The cut-off value for the first postoperative day maximum lactate was determined, and all patients were categorized into two groups according to the cut-off value. Propensity score matching (PSM) was applied between the two groups, and the difference in the incidence of POD was analyzed. Then, we employed univariate logistic regression, multivariate logistic regression, PSM, and inverse probability of treatment weighting (IPTW) models to examine the relationship between the first postoperative day lactate levels and POD.
resultsAmong the 4856 patients enrolled, there was a significant difference in lactate-max on the first postoperative day between patients without POD and patients with POD (median 2.5 vs. 3.1, p < 0.001). The cut-off value of lactate-max was 2.85 mmol/L. For the two groups after PSM, the incidence of POD in the lactate-max ≥ 2.85 mmol/L group was significantly elevated (19.2% vs. 15.9%, p = 0.029). The elevated lactate-max on the first postoperative day was substantially associated with an increased risk of POD in univariate and multivariate logistic regression analyses, PSM, and IPTW models.
conclusionsThe results demonstrated that the first postoperative day lactate-max was correlated with the risk of POD in patients undergoing cardiac surgery, with the POD risk increasing significantly in patients with a lactate-max ≥ 2.85 mmol/L on the first postoperative day.
