Cost-effectiveness
MISCARRIAGE
The cost-effectiveness and outcome were expressed by ratio using the following formula:

The incremental cost-effectiveness ratio (ICER) for live birth was defined as the difference in cost divided by the difference in cumulative live birth rate (CLBR). Similarly, the incremental cost-effectiveness ratio (ICER) for miscarriage prevention was defined as the difference in cost divided by the difference in cumulative miscarriage rate (CMR).
