The footnote for table 3 has been corrected to:

The enzyme range was calculated based on a 90% range of enzymes from natural history data (5,38), which for creatine kinase is 20 times the upper limit of normal (ULN), for aldolase is 6 times the ULN, and for lactate dehydrogenase, aspartate aminotransferase, and alanine transaminase is 5 times the ULN.
