Association between intraoperative hypotension and adverse clinical outcomes after esophagectomy for esophageal cancer: retrospective observational study.

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
backgroundEsophagectomy for esophageal cancer is complex and frequently complicated by pulmonary issues, cardiac problems, and anastomotic leakage. While numerous factors contribute to these complications, the specific effects of intraoperative hypotension (IOH) on postoperative outcomes remain poorly understood. This study examined the relationship between IOH severity during esophagectomy and subsequent complications.
methodsThis retrospective observational study analyzed patients undergoing elective open transthoracic or thoraco-laparoscopic esophagectomy for esophageal cancer between May 2007 and February 2020. Multiple logistic regression assessed IOH's association with primary outcomes (composite of major complications including 30-day mortality, reoperation, anastomotic leakage, pneumonia, reintubation, and prolonged ventilation > 48 h) and secondary outcomes of anastomotic leakage. Additionally, Cox regression analyzed IOH's impact on long-term prognosis.
resultsThe final cohort comprised 884 patients. The most prevalent postoperative complications were anastomotic leakage (25.2%) and pneumonia (23.4%). The 30-day mortality rate was 0.8%. No significant association existed between IOH and major composite outcomes across mean blood pressure (MBP) and systolic blood pressure thresholds. However, IOH was significantly associated with anastomotic leakage when MBP fell below 65 mmHg for extended periods (adjusted odds ratio: 1.02 per 10-min interval, 95% confidence interval: 1.01-1.04, P = 0.01). IOH did not significantly affect long-term survival.
conclusionsThis study did not identify a significant association between intraoperative hypotension and composite major postoperative complications or long-term survival outcomes. However, intraoperative hypotension, specifically prolonged episodes with mean blood pressure below 65 mmHg, was significantly associated with the short-term complication of anastomotic leakage.
