Figure A1.

The relationship between the concentration of acetylcholine (Ach) and the NO-mediated (so-called endothelium-dependent) arterial relaxation in experimental groups subjected to different diets, created from real Ach concentration-response (E/c) curves presented on Figure 3. The axis x shows the common logarithm of molar concentration of Ach, and the axis y indicates the effect as a percentage decrease of the initial contractile force. The symbols show the modified effect values averaged within the groups (±SEM), and the lines denote the Hill equation fitted to the averaged modified Ach E/c data.
