Data are .†Mean ± SD of -score values or ‡mean ± SD of -score values. Mean ± SD of IQ values. According to the STROBE guidelines, no value is given [20]. $Given that few participants failed to finish all cognitive tests, the number of participants who performed completely cognitive testing is given for each test.
