So I think it's incumbent on us at this stage to to treat patients as individuals and utilize a combination of non-invasive and invasive testing with stress to tease out if the primary problem is a vascular resistance problem through the lung circulation, if the primary problem is ventricular stiffness, or if the primary. The problem is a substantial combination of both and target their therapies towards what we have and what we can use to those specific problems in our future.
