Mean change from baseline of outcome measures, and difference in scores between the placebo and indomethacin group, after six months and one year of treatment.

Negative change in scores from baseline indicates improvement, with the exception of the MMSE score (positive change indicates improvement), and the CIBIC+ (higher score means worse compared to baseline).
Positive difference between groups means in favor of the indomethacin group, for all measures.
