q3 · i? · quant-synthesis · r3

Risk-for-bias assessment of the 27 included studies using selection and information bias categories. The review reports "100% of included studies were coded as high risk for selection bias" and that 48.1% had high and 18.5% moderate risk for information bias.

"Concerningly, 100% of included studies were coded as high risk for selection bias, meaning that the representativeness of the included studies' samples to the population is in question. Most often, studies consisted of convenience samples or samples with low response rates."

• The methodological quality of forest-school studies is poor: most are at high or moderate risk of bias, with no follow-ups and inadequate statistical procedures — related
