  1. Notes: In the above table model 1 & 5 is Stratified matching; model 2 & 6 is Radius matching (radius = 0.01); model 3 & 7 is Kernel matching; and model 4 & 8 is Inverse Probability Weighting (IPW) by logistic regression. The IPW results are Odds Ratios [OR] while the matching results are percentage points differences. The standard errors are bootstrapped. Significance levels: ***p < 0.01, **p < 0.05, *p < 0.1. The results presented in the table above are for the matched samples only
