Table 3_Neutrophil-to-lymphocyte ratio as a harbinger of peritonitis in peritoneal dialysi

178 patients from a single-center retrospective case-control study were analyzed to assess the neutrophil-to-lymphocyte ratio (NLR) as a predictor for peritoneal dialysis-associated peritonitis (PDAP). The dataset, authored by Wenhui Lei and last updated in April 2026, contains results from logistic regression analyses showing a significant association between higher NLR and increased PDAP risk. An elevated NLR demonstrated moderate discriminative ability with an area under the curve of 0.78.

Use Cases

• Train binary classification models to predict peritonitis risk based on pre-infection NLR levels.
• Validate the dose-response relationship between NLR and infection risk using the reported continuous and categorical odds ratios.
• Benchmark new predictive biomarkers against the reported AUC of 0.78 for NLR.
• Conduct meta-analysis by combining these case-control results with similar studies on inflammatory markers.

Strengths

• Includes 178 patients (89 cases and 89 matched controls), providing a matched study design.
• Reports specific statistical results, including an odds ratio of 11.00 for the highest NLR tertile and an AUC of 0.78.
• Covers a 14-year time range from January 2010 to October 2024.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Data is from a single center, which may limit generalizability.
• The dataset is very small at 12.9 KB, indicating limited scope, likely containing summary results rather than raw patient-level data.
