What happens if the replays are inconclusive?

If, despite the available technology, the third umpire cannot decide with a high degree of confidence whether the original on-field decision should be changed, they report that the replays are "inconclusive" and the on-field decision stands. The third umpire does not give answers conveying likelihoods or probabilities.
