Factors associated with postoperative acute kidney injury in stanford type a aortic dissection in china: a systematic review and meta-analysis.
Synthesis in Journal of cardiothoracic surgery, 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
objectiveThis study aimed to explore the factors associated with postoperative acute kidney injury in Chinese Stanford type A aortic dissection patients through a systematic review and meta-analysis.
methodsCNKI, WanFang Database, VIP, SinoMed, PubMed, Web of Science, Embase and Cochrane Library were comprehensively searched from inception until September 2025. Two reviewers independently conducted study selection, data extraction, and quality assessment. Meta-analysis was performed using Stata 15.1 and R 4.5.0 software. The certainty of evidence was evaluated using the GRADE tool.
resultsA total of 47 eligible studies comprising 9077 patients were included. Based on these observational studies, which predominantly had low to very low certainty of evidence (GRADE), the following factors were found to be associated with postoperative AKI in Chinese Stanford type A aortic dissection patients: age[adjusted odds ratio (OR) = 1.10, 95% confidence interval (CI): 1.03-1.19, p < 0.05], BMI[OR = 1.20, 95%CI: 1.17-1.24, p < 0.001], hypertension history[OR = 2.74, 95%CI: 2.34-3.21, p < 0.001], renal artery involvement[OR = 4.40, 95%CI: 2.81-6.91, p < 0.001], preoperative cardiac tamponade[OR = 3.47, 95%CI: 1.93-6.26, p < 0.001], preoperative serum creatinine[OR = 1.16, 95%CI: 1.09-1.23, p < 0.001], preoperative platelet[OR = 0.96, 95%CI: 0.92-1.00, p < 0.05], preoperative serum myoglobin[OR = 1.69, 95%CI: 1.44-1.98, p < 0.001], preoperative serum cystatin C[OR = 6.59, 95%CI: 3.77-11.50, p < 0.001], cardiopulmonary bypass time[adjusted OR = 1.01, 95%CI: 1.00-1.02, p < 0.05], CPB > 180 min[OR = 3.48, 95%CI: 1.65-7.30, p < 0.01], operative time[OR = 1.69, 95%CI: 1.33-2.14, p < 0.05], deep hypothermic circulatory arrest time[OR = 1.16, 95%CI: 1.10-1.22, p < 0.001], aortic cross-clamp time[OR = 1.11, 95%CI: 1.01-1.21, p < 0.05], intraoperative RBCs transfusion volume[adjusted OR = 1.17, 95%CI: 1.02-1.35, p < 0.05], intraoperative urine output[OR = 0.75, 95%CI: 0.64-0.88, p < 0.001], mechanical ventilation time[OR = 1.01, 95%CI: 1.01-1.02, p < 0.001] and postoperative procalcitonin[OR = 1.03, 95%CI: 1.01-1.06, p < 0.05].
conclusionThis study demonstrates that factors associated with postoperative acute kidney injury in Chinese Stanford type A aortic dissection patients are closely related to the perioperative period. These findings may help clinicians identify risk factors early and facilitate the development of preventive strategies to improve patient outcomes.
