$
Year 1 correlations were not included since there was no previous treatment coverage to compare with the Year 1 prevalence.
-nsIndicates counties which had not had routine parasitological monitoring, hence, surveys were not conducted in these counties during Year 1, Year 3, and Year 5 assessments.
*
Indicates a statistically significant negative correlation.
#
Indicates a statistically significant positive correlation.
°
Indicates a strong significant correlation (defined as r > |0.7|, p <0.001) (i.e. values in gray shade).
