Inverse J-Shaped relationship between change in SBP at orthostatism and walking speed (A) or hand-grip strength (B). There was an inverse second-order polynomial relationship between change in SBP after 3 min of orthostatism and walking speed (ßadjusted = -0.71 [-1.2; -0.25]; p = 0.003) and hand-grip strength (ßadjusted = -12 [-23; -1.1]; p = 0.032). The 95% confidence interval of each relationship is shown by the shaded area. ∆SBP 3’ change in systolic blood pressure after 3 min of orthostatism
