Subsequently, sample source subgroup analysis indicated a significant association between NSE levels in the CSF and epilepsy in children [Hedges' g = 2.005 (95% CI = 1.169–2.840); P < 0.001] ( Figure 4B ); similarly, studies using serum as the sample source indicated highly significant results [Hedges' g = 1.932 (95% CI = 1.189–2.675); P < 0.001].
