^^ The conclusion here is obvious and reflects standard treatment. Nobody operates on asymptomatic patients. In fact, hardly anyone operates on symptomatic patients unless the herniation is quite severe and has not responded to other therapies. (A flaw in this "groundbreaking" study, unless you've left out important information, is that there's no mention of the SEVERITY of the herniations in these asyptomatic patients; that asymptomatic persons can have trivial herniations has long been known.)
