title: A model for cross-over trials evaluating therapeutic preferences.
abstract: A preference trial is a special form of cross-over trial where clinical conditions determine when patients change treatment, in a prescribed order. This can be modelled using a geometric distribution. The model can be simply fitted using standard logistic regression methodology. The procedure is applied to a trial studying the effects of bronchodilators in the treatment of chronic asthma.
