Afib = Atrial fibrillation Hip Fx = Hip Fracture CEA = Carotid Endarterectomy HSG = Hysterosalpingography * Characterizations or comparisons were given an 'A' if they included least one element in each of the following categories: demographics, medical history, and clinical assessment. They were given a 'B' if they included one medical history or clinical assessment variable, a 'C' if they included one demographic variable, and a 'D' if there were no characterization or comparisons. ↖ Treatment selection methods were given an 'A' if they probably reduced confounding, a 'B' if the effect on confounding was uncertain, a 'C' if confounding was probably increased, and a 'D' if they were not described. † Statistical adjustment was given an 'A' for using multiple regression, 'B' for using stratification, and 'C' for no adjustment. | ||||||||
