So 4/26 athletes had elongated T2, in an uncontrolled study, with no pre-exposure baseline measures. This is one-half step above meaningless. The only argument they have is that the other 22 athletes had a mean T2 of 51, vs 59 for the four in question. The highest reported “abnormal” time is 63ms. The others are 55, 59 and 61ms. Here is the first set of slides I found for topic from a presentation by a doctor at Columbia University. Slide 14 shows the distributions of T2 times for several control and disease groups. You’ll note that the control group runs from 50-61ms: https://cdn.ymaws.com/scmr.org/resource/resmgr/2019/new_york/maehara,_akiko_-_consensus_c.pdf https://cdn.ymaws.com/scmr.org/resource/resmgr/2019/new_york...
