Figure 1.

A, Presenting neurologic symptoms by age in 365 patients (age <21 years) with COVID-19–related neurologic involvement. B, Most abnormal laboratory results in 1695 patients (age <21 years) with COVID-19 by severity of neurologic involvement. Denominators varied and are provided in eTable 6 in Supplement 1. FEU indicates fibrinogen equivalent units.

SI conversion factors: To convert C-reactive protein to mg/L, multiply by 10; D-dimer to nmol/L, multiply by 5.476; hemoglobin to d/L, multiply by 10; platelet count to ×109/L, multiply by 1.

aNeutrophilia was defined as a maximum absolute neutrophil count higher than 7700/μL.

bLymphocytopenia was defined as an absolute lymphocyte count of less than 1500/μL in patients 8 months or older and of less than 4500/μL in patients younger than 8 months.
