The mean age was 3.1 years. Data were collected cross-sectionally. Cardiometabolic health was assessed using an objective measure of blood pressure.
276 (1)	Cross-sectional^a	Serious risk of bias^b	No serious inconsistency	No serious indirectness	No serious imprecision	Screen-based sedentary behaviours: Watching TV for ≥ 2 h/day was not associated with high blood pressure (compared to <2 h/day, Prevalence Ratio = 0.9, 95% CI: 0.5, 1.4, p = 0.568) [126].	Very low^c

^aIncludes 1 cross-sectional study [126]

^bSerious risk of bias. Unknown reliability and validity of the exposure measure [126]

^cThe quality of evidence from the cross-sectional study was downgraded from “low” to “very low” because of a serious risk of bias that diminished the level of confidence in the observed effects
