Euler diagrams are presented for neonates (A), infants (B), and children (C). Patients who went under lumbar puncture (LP) are pinpointed (each point represents 1 LP) according to their clinical presentation. Point colors represent the ultimate neurological diagnosis after evaluation by the DeCoDe panel. The bar beneath each age group represents the proportion of final diagnoses among children who underwent an LP (46 neonates, 31 infants, and 18 children). Dots outside of the bars represent children without any neurological symptoms who underwent an LP. Euler diagram errors: 0.001 in all age groups; stress: less than 0.01 in all age groups. AM indicates altered mental status; DeCoDe, Determination of Cause of Death; F, fever; MS, meningeal sign; and S, seizure.
