Fig. 2: Trajectories of NIRS parameters by postnatal days and PHVD burden.

Trajectory of rScO2 (a), cFTOE (b), Time <55% rScO2 (c), and Fluctuation (d) plotted by postnatal age (in days) for patients with IVH+PHVD and no temporizing neurosurgical intervention (tNSI), a single tNSI and multiple tNSIs. Solid/dashed lines indicate LOESS non-linear regression curves, with gray shading representing the 95% confidence interval.
