UNETR Papar BTCV five-fold cross validation

[shuozhang7979]

Thanks for your great works. But we have a typo question about the paper.

In the section 4.3 of UNETR paper, you have said the following sentence about the BTCV implementation details: For all experiments, we employed five-fold cross validation with a ratio of 95:5.

If my understanding is right, the ratio of five-fold cross validation should be 4:1, but here in the paper you have said 95:5 (names 19:1). which confuses us so much.

Could you plz show me the right insight into this sentence? Thx a lot.
