Definition 3: <12 month vs. >=12 month
No difference in length of stay was showed (MD, 1.32; 95% Cl,-3.80 to
6.44; P=0.61) with very high heterogeneity (I2=95%). Deleting the
Dukleska2017, the heterogeneity droped from 95% to 0%, the p-value was
statistically significant (P < 0.00001). But the reason can’t
be found. The publication bias of the length of stay was assessed. None
was detected.
In sum, to decrease the length of stay, it’s well to operate the surgery
between 3 months to 6 months old, no more than 12 months old in
patients.
