Respiratory support, position during lumbar puncture and additional information on performing lumbar puncture.

	Lumbar punctures N = 204
No respiratory support, n (%)†	84 (41.2%)
Respiratory support during LP, n (%)
- Low or high-flow nasal cannula, nCPAP‡	88 (43.1%)
- Mechanical ventilation¶	32 (15.7%)
Position during LP, n (%)¥
- Sitting only	121 (61.4%)
- Lateral recumbent only	76 (38.6%)
Duration of LP, median minutes (IQR)	5 (3–0)
LP failure, n (%)	78 (38.2%)

IQR, interquartile range; LP, lumbar puncture; nCPAP, nasal continuous positive airway pressure.

^†One infant had body weight at LP <1,500 g.

^‡Sixteen infants had body weight at LP <1,500 g.

^¶Twenty-three infants had body weight at LP <1,500 g.

^¥Seven lumbar punctures were performed with multiple attempts both in sitting and lateral recumbent positions. Rates are calculated on the remaining 197 LPs performed in sitting or lateral recumbent position only.
