Has anyone tried to apply the following regression eqation appeared in the paper "Continuous measurement of systolic blood pressure using the PTT and other parameters" (Proceedings of the 2005 IEEE Engineering in Medicine and Biology 27th Annual Conference Shanghai, China, September 1-4, 2005):(adsbygoogle = window.adsbygoogle || []).push({});

SystolicBP = 85.862 -119,27 PTT +0.259 weight + 0.439 arm length

(Blood pressure in mmHg, PTT is Pulse Transit Time[ms], weight[Kg], arm length[cm])

Nice linear relationship but I get absurd values for BP.

Any help is greatly appreciated.
