Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? In a national cross-sectional survey of 20,778 Chinese school-aged children, 64.44% showed daytime sleepiness (37.50% sometimes, 26.94% frequently). → Li Shenghui 2013

q3 · i? · associational · r2
National cross-sectional survey of 20,778 children aged 9.00 years (SD = 1.61) in eight Chinese cities, using the parent-administered CSHQ. The survey found "daytime sleepiness was shown to be 37.96% and 64.44%" for short sleep and sleepiness respectively, with sleepiness rated on the CSHQ 3-point scale.
"The prevalence of short sleep duration (<9 hours per day) and daytime sleepiness was shown to be 37.96% and 64.44% (sometimes 37.50% vs. frequently 26.94%), respectively."
Discussion¶
Related Claims¶
- Only 22.34% of Chinese school-aged children get sufficient sleep (≥10 hours), while 37.96% have short sleep duration (<9 hours) — related
- In the intervention trial, short sleep prevalence fell sharply in delayed-start schools (intervention 2: 40.47% to 11.87%) while sufficient-sleep prevalence remained low overall — related
- Delaying school start time by 30 or 60 minutes increased children's sleep duration and reduced daytime sleepiness over two years — related
- Frequent daytime sleepiness is associated with impaired academic achievement, attention, and learning motivation in school-aged children — related
- Sleep problems are common in school-aged children, with prevalence estimates ranging widely depending on assessment mode and definition — a broader claim this one bears on
