+PVAT-ENDO	324.3 ± 33.3§	479.5 ± 28.2*§
−PVAT-ENDO	383.7 ± 28.7†	490.1 ± 52.3*
+PVAT+ENDO+l-NAME	273.9 ± 30.3§	481.4 ± 69.3*§

AUC, area under the curve.

^*P < 0.05 vs. SS.13^BN;

^†P < 0.05 vs. −PVAT+ENDO within same rat strain;

^§P < 0.05 vs. +PVAT+ENDO within same rat strain. For SS.13BN rats, n = 8–10. For Dahl SS rats, n = 5–9.
