We are concerned with the non-oscillatory behaviour of a second order linear quasi-differential equation defined a.e. over a half-line. More particularly given that (py')' + qy = 0 is non-oscillatory we show that by writing q in a form which is amenable to further analysis we can generalise Sturm's comparison theorem.
