Standardized b coefficients for two robust regression models describing the relation between the expression levels of five sperm miRNAs and the 56-day non-return rate of 15 bulls recorded after artificial insemination with unsorted (orange) and sex-sorted (blue) cryopreserved sperm, respectively. Transparent points represent the mean of the standardized coefficient b, the horizontal line the 95% confidence intervals and the thicker part of the line the 90% confidence intervals of the estimated coefficients
