Graft uptake rate
All twenty-two studies included data about graft uptake rate with a
total number of interventions (n=1559). Accrued results (Figure 4A)
showed that ET was as effective as MT (89.8% vs. 90.2%;
OR: 0.95; 95% CI 0.68 to 1.34; p = 0.79). In addition, no heterogeneity
(I2 = 0%, p = 0.99) or publication bias was found
(Figure 4B).
