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
purposeThe association between surgical Apgar score (SAS) and clinical outcomes among patients undergoing esophagectomy remains uncertain now. This study aimed to further identify the predictive role of SAS for postoperative complications and survival in patients receiving esophagectomy.
methodPubMed, EMbase and Web of Science databases were searched up to March 27, 2025. Primary endpoints included the postoperative overall complication (OC) and overall survival (OS) and secondary endpoints consists of specific complications and disease-free survival (DFS). Odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CIs) were combined to assess the predictive value of SAS for complications and survival, respectively.
resultsTen studies with 2453 patients were included. Pooled results demonstrated that SAS was significantly related to the risk of overall complications (OR = 0.43, 95% CI: 0.33–0.57, P<0.001), but not associated with OS (HR = 0.84, P = 0.246). Furthermore, a low SAS predicted increased risk of anastomotic leakage (OR = 0.44, P = 0.004), chylothorax (OR = 0.33, P = 0.020), infection (OR = 0.43, P<0.001), 30-day mortality (OR = 0.40, P = 0.011), pneumonia (OR = 0.61, P = 0.037), reintubation (OR = 0.29, P = 0.003), respiratory complication (OR = 0.49, P = 0.014), gastrointestinal complication (OR = 0.57, P = 0.035), length of stay (OR = 0.60, P = 0.038), pulmonary complication (OR = 0.46, P = 0.003). However, SAS was not associated with the risk of other complications such as the cardiac complication (P = 0.215) and sepsis (P = 0.087) and DFS (P = 0.341) in esophageal cancer patients.
conclusionSAS may serve as novel prognostic indicator for postoperative complications in patients receiving esophagectomy and low SAS predicts increased risk for complications. However, more studies are needed to further verify above findings.
