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.
q2 i? Children in the later, shorter, inconsistent class had later weeknight sleep timing, shorter weeknight and weekend sleep duration, less consistency in sleep-related behaviors, and higher caffeine consumption within 3 hours of bedtime. → Turnbull Khara L.

Latent class analysis findings describing Class 2 (13% of the sample), contrasted with Class 1 in Table 1 and Figure 1 item means. The article states this class is "characterized by later weeknight sleep timing, shorter weeknight and weekend night sleep duration, less consistency in sleep-related behaviors, and higher caffeine consumption within 3 hours of bedtime."
"This class is characterized by later weeknight sleep timing, shorter weeknight and weekend night sleep duration, less consistency in sleep-related behaviors, and higher caffeine consumption within 3 hours of bedtime."
