Abbreviations: n, number of participants; WG cFSIQ = FSIQ corrected with the Whitaker and Gordon method; IQR, interquartile range; Min – Max = minimum and maximum values; MOR, methylation output ratio; FSIQ, Full Scale IQ; *p-value for testing normal distribution of a variable using Shapiro-Wilk test; values less than 0.05 are considered significant, indicate a not normal distribution and are highlighted in bold.
