PSM: propensity score matching. Data had been matched by using propensity score matching with 1 : 1 nearest neighbor matching. Hosmer and Lemeshow goodness of fit (GOF) test; X-squared (χ2) = 10.081, df = 7, P value = 0.188. McFadden's pseudo-R squared = 0.229. Cox and Snell pseudo-R squared = 0.190. Nagelkerke pseudo-R squared = 0.316.
