Well that just seems like a bad study. If restricting phone use at school doesnt actually lower phone use at school then that just means the school didnt enforce the rules…
Thats whate they are saying with that first sentence right? Restrictive rules are not associated with phone use. Thats only possible if the rules arent being applied.
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.
The Lancet is one of the most respected journals of them all - and this is the largest and most scientifically valid study done on mobile phone use in schools.

That means they use the word “overall” to mean “out of school” in a study about school rules. Bravo.
The correct wording would be:
