From the VAERS matching of call center cases (loader/vaers_match_*). Only the best match is shown, and only if it scores 8 or more out of 11. The score adds up timing (VAERS received soon after the call center contact), dose and shared symptoms; state only breaks ties. Confidence is high when the score is 8+ and at least 3 points ahead of the runner-up, medium when 5+ and 2 ahead, otherwise low. A match is a likely link, not a confirmed one.
