Source note
Note (Swedish)
Italiensk naturalistisk jämförelse under covid: samma skola, klasser med 8:00 respektive 9:40 start. Bättre naturvetenskapliga betyg (studie 1) och globalt snitt (studie 2). Sömn mättes inte i den här artikeln (författarna hänvisar till tidigare litteratur). Därför inte ett kill-condition-test för C14 (som kräver uppmätt sömn och/eller mer sömn utan betygsvinst).
