Subclaims¶
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? Penalized splines in generalized additive models showed a nonlinear association of sleep duration with school performance at follow-up (p = 0.04), shown in Figure 2. → Li Shenghui 2013

q3 · i? · associational · r2
Cohort analysis using penalized splines in generalized additive models with generalized cross validation for smoothing selection; gender, age, BMI, family income, family structure, and parents' education were controlled. The authors "observed a nonlinear association of sleep duration with school performance (p = 0.04)", leading them to model sleep duration categorically.
"Using penalized spline of sleep duration, we observed a nonlinear association of sleep duration with school performance (p = 0.04) (as shown in Figure 2 )."
Discussion¶
Learner Variables¶
- Sleep — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Short sleep duration (<9 hours) at follow-up is associated with impaired academic achievement, while baseline sleep duration did not significantly predict later school performance — related
- Adolescents with 7 hours or less total rest time show longer 3-back response times, both acutely and averaged over the week — related
- Older adolescents show high night-to-night variability in free-living sleep duration, which may obscure sleep-cognition associations — related
- Frequent daytime sleepiness is associated with impaired academic achievement, attention, and learning motivation in school-aged children — related
