^a no upgrading factors for all outcomes;

^b <30% from low risk of bias;

^c I²>50% or wide variability in point estimates;

^d Wide pooled 95% CIs or few studies with small samples and imprecise estimates;

^e Heterogeneity substantially alters pooled estimate;

^f Evidence of reporting bias or <10 studies investigating the relationship;

^g ●: no association;

▲: hop test measure was associated with increased likelihood of RTS or decreased odds of reinjury;

▼: hop test measure was associated with decreased likelihood of RTS or increased odds of reinjury;

◆: inconsistent results; ⅹ: no limitations to downgrade;
