In the original medical-statistical review for the Capricorn study, the reviewers expressed some concern about the discrepancy between the overall mortality result (which favors carvedilol) and the mean or median time to mortal event among subjects who died (which seems longer on placebo; see Table 10). While the observation is correct, the interpretation as a discrepancy is not.

If two survival curves separate late, as the curves do in Capricorn, then this outcome seems quite likely.

In summary, the medical and statistical reviewers find no compelling internal inconsistencies in the mortality data of Capricorn.
