  1. aN was number of observations used for each model. All the models were controlled for age groups, whether each of the interventions was received, as well as interaction between age groups and before or after the intervention
  2. bGeneralized linear mixed model using beta distribution was applied to predict α (°), while generalized estimation equation was used for other outcomes. Estimates were predicted marginal means
  3. CI confidence interval, CT clotting time, MCF maximum clot firmness
  4. p values in bold represent statistical significance
