Results from 2-way nested ANCOVA in SAS Procedure Mixed. Replicate line was included as random effects in analyses. Age, time of day, and (time of day)2 were additional covariates (results not shown). + indicates direction HR>C, females>males, or mini>normal. P values are 2-tailed except for HR vs C, where values are 1-tailed. Significant values (P<0.05) are in bold
