Subsequent multiple linear regression analysis (control age and birth weight) revealed that the BDNF level in pregnant women with SCH was positively associated with NBNA total score (β = 0.49, t = 4.26, p < 0.001), behavioral capacity (β = 0.32, t = 2.71, p < 0.01), active muscle tension (β = 0.54, t = 4.36, p < 0.001), and general assessment (β = 0.34, t = 2.54, p < 0.01). Here, BDNF is linked to spindle cell hemangioma.
