Blood pressure levels measure by radiotelemetry in SHR parental lines SHR-A3 and SHR-B2 and in the F2 progeny of a cross between these lines. The only statistically significant differences when comparing across the four groups of animals was between SHR-A3 and the F2 A3 XB2 (p<0.05). Statistical analysis in multiple group comparisons was performed by ANOVA followed by Tukey's HSD test of significance.

| SHR-A3 | 16 | 198.6 | 3.9 | 171.7 | 3.2 | 144.6 | 2.8 |
| SHR-B2 | 20 | 186.7 | 2.5 | 158.8 | 3.3 | 136.3 | 2.6 |
| F1 A3 × B2 | 13 | 195.0 | 4.6 | 160.1 | 1.7 | 133.8 | 2.0 |
| F2 A3 × B2 | 121 | 184.0 | 1.3 | 158.1 | 1.4 | 132.3 | 1.3 |
