INT = intervention group | CTR = control group
NE = north-east quadrant of the cost effectiveness plane, which indicates the intervention is more effective and more costly than the control condition | SE = south-east quadrant of the cost effectiveness plane, which indicates the intervention is more effective and less costly than the control condition | SW = south-west quadrant of the cost effectiveness plane, which indicates the intervention is less effective and less costly than the control condition | NW = north-west quadrant of the cost effectiveness plane, which indicates the intervention is less effective and more costly than the control condition
