Similarly, we have observed that the application of MSCs or BMP-7 was not statistically associated with an improved incidence of efficient healing outcome between the treated and non-treated cases with long bone fractures (I2 = 72%, 95% CI = 3.23 [0.52–20.01], Z = 1.26, p = 0.21) and (I2 = 8%, 95% CI = 0.71 [0.37–1.36], Z = 1.03, p = 0.30), respectively. Here, BMP7 is linked to bone fracture.
