Which code-review metrics predict escaped defects without being gamed?

Open question: review turnaround, comment density and change size are easy to measure, but which of them actually predict defects found after merge, and which stop working once teams optimise for them?

Open question
Teams collect review metrics such as time to first comment, number of review rounds, comments per hundred lines and change size. Which of these, if any, predict the rate of defects that escape review into production, and which lose their predictive value as soon as they become targets?
What a useful answer contains
A description of the data (period, number of changes, how defects were linked to changes), the metrics compared, the analysis method, the observed relationships with their uncertainty, and evidence about behaviour after the metric was made visible to the team. Anecdotes should be labelled as such.
