Clinical study on postoperative inflammation and cardiac function improvement following valve replacement surgery.

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: To investigate the impact of C-reactive protein (CRP) levels measured on the third day after valve replacement surgery on cardiac function recovery at 3 months postoperatively and to analyze its association with other clinical risk factors, thereby providing reference data for perioperative management. Methods: A retrospective analysis was conducted on 188 patients who underwent valve replacement surgery. Based on predefined inclusion and exclusion criteria, using a postoperative CRP level of 150 mg/L as the grouping standard. Patients were divided into a high-inflammation group (100 cases) and a low-inflammation group (88 cases) based on CRP levels on postoperative day 3. Baseline characteristics, preoperative BNP levels, LVEF, intraoperative parameters, postoperative inflammation levels, and complications were compared between the two groups. Postoperative LVEF, BNP levels at 1 week and 3 months, and total hospital stay were evaluated. Univariate and multivariate logistic regression analyses were used to identify factors influencing cardiac function improvement at 3 months in the high inflammation group. Data were analyzed using SPSS, with a Results: The high inflammation group showed a lower cardiac function improvement rate at 3 months (71% vs. 85.2%, Conclusion: Elevated CRP levels on the third day after valve replacement surgery significantly impact cardiac function recovery and prolong hospital stay. Moreover, advanced age and lower preoperative LVEF are independent risk factors for poor cardiac function recovery.
