On page 32 of the report it states;

Therefore, if an audio attention-getter is acknowledged (and cancelled) by the pilot, a snapshot will be recorded with the remaining, uncancellable visual element (caption) shown as active. If a warning condition ceases, then both the audio (if still present) and visual elements will switch to the inactive state in new snapshot.


Table 3 shows three occasions when after cancelling the audio the caption light became inactive. This could imply that the warning condition had ceased.

Again on page 32 of the report it states;
The WU contains NVM which records a snapshot of the state of all visual and audible warnings when the status of one of them changes




How do we know that the status changes identified in table 3 were intiated by the pilot?
