CJC-1295 with DAC by quarter
Coverage and results for CJC-1295 with DAC quarter by quarter. Read the supplier-count column beside the median: a quarter where the compound mix changed is not comparable with the one before it, and the index cannot hold that constant retrospectively.

Median purity by quarter
Quarters with fewer than two purity records are gaps in the line rather than zeroes. A trend across 11 points, most of them thin, is a shape and not a finding.
