Fig. 7From: The Shiny Balancer - software and imbalance criteria for optimally balanced treatment allocation in small RCTs and cRCTsBalancing on multiple variables in data set 1 (left) and data set 2 (right). Allocation schemes are represented by quadrangles whose vertices indicate the standardised imbalance contributions from individual variables of given types according to the specified metrics. Black: 10 schemes with smallest total imbalance; dark grey: 90 “next best” schemes; light grey: all generated schemesBack to article page
