Mdn = median; IQR = interquartile range (1. quartile; 3. quartile); MSPSS = Multidimensional Scale of Perceived Social Support; p = p-value
^aFisher’s exact test
^bMann–Whitney U test
^cLikert scale ranges from 1 to 7; high scores indicate higher levels of perceived social support
^dLikert scale ranges from 0 to 4; higher values higher mean resilience
