From: High disease activity correlate with decreased serum calcium in systemic lupus erythematosus

Two follow-up analyses of 15 SLE patients within one year. Two follow-up visits are represented by 1st and 2nd, respectively. Serum calcium levels increased during the second follow-up after treatment. 15 patients labeled as A-O and each point represents a patient. p < 0.05 was considered as a statistically significant.
