Relativity (Physics). ; Anisotropy -- Mathematical models. ; Einstein field equations. ; Newtonian fluids. ; Astrophysics.
We study the effects of anisotropic pressure on the properties of spherically symmetric, gravitationally bound spheres. We consider the full general-relativistic and Newtonian treatment of this problem and obtain exact solutions for various forms...

Several ""health state classification systems"" are available to estimate health state values (HSV) for economic evaluation. Evidence of variation in estimates from different systems raises concern that system choice may affect study conclusions...
