1. Revision 3Oct 4, 2026, 3:57 PMLiveAI-organised, reviewed

   Adds four newer syntheses and studies (a 158-study scoping review, a 2-5 year neurocognitive review, a longitudinal coviewing study, and a Thai cross-sectional study) that sharpen the quantity-versus-quality picture and add dose-response odds ratios. Keeps the existing finding and guidance, adds guidance on recreational versus educational content and on violent content, and notes that coviewing and educational content did not offset higher screen time in the longitudinal study.
