A fragility-style stability metric computed by removing events instead of adding them.
The fragility index estimates how many outcome events would need to change to flip a trial's statistical significance; the 'reverse' and 'continuous' variants are non-standard extensions that instead count how many events could be removed before significance is lost, using a continuous (non-integer) event-counting approach rather than the usual whole-event method. This terminology is not standardized in the fragility-index literature, so its exact calculation should be verified against the source study rather than assumed. It is a statistical robustness metric, not a direct measure of clinical effect size.
