Table 1 Demographic characteristics and preoperative inflammatory indices in patients.
| Variable | PDPH (+) | PDPH (−) | P value |
|---|---|---|---|
| NLR (median [IQR]) | 2.63 (2.26–3.13) | 3.82 (3.22–4.61) | <0.001* |
| PLR (median [IQR]) | 126.79 (103.87–150.64) | 127.75 (102.49–157.84) | 0.729 |
| MLR (median [IQR]) | 0.31 (0.23–0.40) | 0.31 (0.24–0.39) | 0.8891 |
| Age (mean±sd) | 28.6±4.3 | 28.0±4.4 | 0.114 |
| BMI (mean±sd) | 30.1±3.2 | 30.6±3.0 | 0.188 |
| SIRI (median [IQR]) | 1.60 (1.15–2.13) | 2.08 (1.60–2.78) | <0.001* |
| The data are presented as mean±standard deviation (SD) for normally distributed variables (age and BMI, compared using the test) and as median (interquartile range [IQR]) for non-normally distributed variables (NLR, PLR, MLR, and SIRI, compared using Mann-Whitney U test). PDPH (+): n=133; PDPH (−): n=688. BMI – body mass index; PDPH – post-dural puncture headache; NLR – neutrophil-to-lymphocyte ratio; PLR – platelet-to-lymphocyte ratio; MLR – monocyte-to-lymphocyte ratio; SIRI – systemic inflammation response index. * Statistically significant at | |||
