Using data from the Women's Health Initiative (WHI) calcium plus vitamin D supplementation trial, researchers identified a subgroup of 1,911 postmenopausal women for the current study, who had been randomized to receive calcium carbonate with vitamin D3 daily or placebo and had undergone serial joint symptom assessment. Responses to a questionnaire provided qualitative information on joint pain and joint swelling before entry and two years after randomization.
