A. Skin microfilaria density pre-treatment by sex of participant and number of onchocercal nodules.

<p>B. Skin microfilaria density pre-treatment by number of live female macrofilariae and sum of live (LI) and dead, non-calcified female macrofilariae (LIDD). Only data from participants who had not more palpable nodule sites at month 18 than at pre-treatment and who had agreed to excision of all palpable nodules or who had no palpable nodules are included. For display reasons, the×axis maximum in Figure B was set to 9. The data from the man with 8 nodules in Figure A who had 13 live female macrofilariae and 3 dead, non-calcified female macrofilariae and 50.2 mf/mg skin pre-treatment are thus not displayed.
