Nomogram for subsyndromal delirium after cardiac surgery with cardiopulmonary bypass: a retrospective cohort study.
Article in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: The incidence of subsyndromal delirium (SSD) after cardiac surgery with cardiopulmonary bypass (CPB) is relatively high. In this study, we aimed to analyze the risk factors associated with postoperative SSD and to construct a predictive model to facilitate early identification of SSD, thereby providing an effective clinical prediction tool. Methods: We conducted a retrospective cohort study, including patients who underwent cardiac surgery with CPB at a tertiary hospital in Sichuan Province from January 2023 to March 2024. Clinical nurses performed six daily assessments for SSD by using the Confusion Assessment Method for the Intensive Care Unit until delirium occurred or the patient was discharged from the intensive care unit or died. A total of 994 patients were included and divided into a non-SSD group ( Results: Among the 994 patients who underwent cardiac surgery, the incidence of SSD was 16.30% ( Conclusion: The incidence of SSD after cardiac surgery with CPB was high. The predictive model developed in this study demonstrated good predictive performance and may assist healthcare professionals in the early identification of high-risk patients, enabling timely preventive interventions to reduce the risk of postoperative SSD.
