Association between knowledge of Taenia solium and personally attending a farmer-training workshop and/or receiving one-on-one training with a researcher after controlling for gender, age, and level of education in all small-holder pig farmers involved in a research project in Western Kenya, 2006–2008

*
Questionnaire 2 administered in Busia, Nov 2006 and in Kakamega, Dec 2007 and May 2008; Questionnaire 3 administered in Busia, Feb 2007 and in Kakamega, June and Oct 2008.
†
One-on-one training was given after administration of the second questionnaire.
‡
Although P > 0.05, the variable was kept in the model because of confounding. NS = not significant.
