A + sign indicates that 95% coverage was met, and ‘−’ when the lot quality assurance sampling (LQAS) test was below target. Double ‘−’ signs (− −) indicate areas with poor coverage (under 65%).
Total for all areas equals weighted average for all supervision areas in each state.
↵* Significantly different from baseline (p<0.05).
