Pharmacoepidemiology Toolbox including High-dimensional Propensity Score (hd-PS) Adjustment version 2

*Notification – There are restricted circumstances where the nearest neighbor macro does not identify all matches within caliper (e.g. when the cohort size is large and the c-statistic is low with few unique propensity score values). This issue will be corrected in the next version update. Until the next version is released, a workaround would be to re-run the macro on remaining unmatched patients until no more matches are found.
