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? Students who were overweight or obese at baseline and received both the Get Fit and Prevention components showed reduced BMI z-scores and reduced prevalence of overweight and obesity. → Mabli 2017

The evaluation reports BMI outcomes for the targeted subgroup: students "who were overweight or obese at baseline, and received both Get Fit and Prevention components" showed reduced BMI z-scores and overweight/obesity prevalence. No effect sizes are printed in the available text.

"Reduced BMI z-scores and the prevalence of overweight and obesity among students who were overweight or obese at baseline, and received both Get Fit and Prevention components."

Discussion¶

Learner Variables¶

Physical Well-Being — outcome: instruction changes it

Overweight or obese students who participated in Get Fit and Prevention had large and statistically significant increases in PACER laps two and three years later — related
Healthy Harlem generally increased students' fitness levels, with variation by gender — a broader claim this one bears on
Healthy Harlem had some positive impacts on other measures of student self-efficacy and social support — related
