Concentrations of serum 25OHD for all UIA patients at baseline according to final diagnosis after 12 months. Boxes represent median and interquartile range (IQR), whiskers represent the range, and beyond this any extreme outlier values are also shown. Values for each group are as follows: (i) Remained UIA, n = 58, median 52.0, IQR 29.5–71.0; (ii) Progressed to RA (n = 19, median 48.8, IQR 32.0–61.0); (iii) Progressed to Other; n = 4, median 52.5, IQR 24.7–82.3. There were no statistically significant differences between groups (p = 0.908)
