Fig. 3From: Serum neurofilament light reflects cognitive dysfunctions in children with obstructive sleep apneaMultivariate correlations with neurofilament light (NfL), tau and clinical parameters. The numerical value of each cell is the spearman correlation coefficient. The baseline (r) value (white) is 0, the maximum value (red) is 1, the light green is -0.3, and the dark green is below -0.3. **P < 0.01, *P < 0.05Back to article page
