Non-confounding analysis on LP needle type and volume of CSF drawn on PLPH development
| Type of LP performed | All first ever LP | Baseline only | |||
|---|---|---|---|---|---|
| OR (95% CI) | P-value | OR (95% CI) | P-value | ||
| LP performed with atraumatic needle only | Vol of CSF drawn: | ||||
| 10 mL (Ref) | 1.00 | 0.013 | 1.00 | 0.028 | |
| 20 mL | 0.17 (0.04–0.19) | 0.12 (0.02–0.98) | |||
| LP with 10 mL CSF drawn only | Needle used: | ||||
| Cutting edge (Ref) | 1.00 | 0.068 | 1.00 | 0.087 | |
| Atraumatic | 0.33 (0.10–1.04) | 0.365 (0.11–1.19) | |||
CSF: cerebrospinal fluid; LP: lumbar pucture; PLPH: post-lumbar puncture headaches.
