The prognostic value of perioperative neutrophil-lymphocyte ratio (NLR) as a predictor of outcomes after pediatric cardiac surgery: A systematic review and meta-analysis

Key Points

• This review aims to evaluate the prognostic value of the neutrophil-lymphocyte ratio (NLR) in predicting outcomes after pediatric cardiac surgery.
• Conducted a systematic review of existing literature
• Performed a meta-analysis to synthesize data
• Focused on studies linking NLR with clinical outcomes in pediatric cardiac surgery
• NLR showed potential as an inflammatory marker in predicting outcomes
• Found moderate to weak correlation with actual clinical outcomes
• Highlighted the need for further impact studies to validate findings.
