Adolescents attending schools with restrictive, compared to permissive policies had lower phone (adjusted mean difference −0.67 h, 95% CI −0.92 to −0.43, p = 0.00024) and social media time (adjusted mean difference −0.54 h, 95% CI −0.74 to −0.36, p = 0.00018) during school time, but there was no evidence for differences when comparing usage time on weekdays or weekends.

    There is no evidence that restrictive school policies are associated with overall phone and social media use

    That means they use the word "overall" to mean "out of school" in a study about school rules. Bravo.

    The correct wording would be:

    There is no evidence that restrictive school policies are associated with overall phone and social media use outside of school
