How this was measured

Each fighter's previous UFC bout from the UFC Stats record (doctor stoppages count as KO/TKO). The comparison rate is the KO/TKO-loss rate of all other fighters with a previous UFC bout, weighted to the same division mix (indirect standardisation).

Included

  • Fighter-bouts since 2001 with a winner
  • The fighter's previous UFC bout was a KO/TKO loss

Left out

  • Draws and no contests
  • UFC debuts (no previous UFC bout)
  • Catch weight or open weight (no division baseline) (0)

Caveats

  • Opponents are not matched: matchmaking after a knockout loss is not random.
  • Bouts outside the UFC between the two are not in the data.

How it was checked

  • Reproduced exactly by an independent re-implementation written from the definition alone (28 Oct 2026).
  • Survives the Benjamini–Hochberg correction across all 59 tested research hypotheses (q < 0.001).
  • Research catalog entry `ko_loss_stopped_again` (validated).
