Fig. 5From: Hypertension contributes to exacerbated osteoarthritis pathophysiology in rats in a sex-dependent mannerCardiovascular responses to chemical stimulation of vagal afferents with 1-phenylbiguanide (PBG) in males (top) and females (bottom). A In males, heart rate responses were increased in the hypertensive-MCLT+MMT group compared to normotensive-MCLT+MMT; this decrease was not statistically significant in the male sham groups. B In males, blood pressure responses to PBG were enhanced with hypertension, regardless of the surgical group. C No differences were seen in female heart responses to PBG; however, D hypertension resulted in larger blood pressure drops with PBG administration in the MCLT+MMT surgical groups. This difference was not statistically significant in the sham surgical group. Bars indicate p < 0.05 between the groups. Data are presented as mean ± 95% confidence intervalBack to article page
