title: Selection of patients for clinical trials.
abstract: Since there is no treatment of proven value in patients with MS it is necessary still to select those patients for inclusion in clinical trials who have most to gain and can demonstrate rapidly the effectiveness or not of each new treatment. Experience gained in these trials can be then extrapolated to the disease as a whole.
