Women made up 49% of participants at baseline, with
no difference by community or intervention. GLM
analyses evaluated differences in baseline characteristics
by condition (PLSP vs control), community (1, 2 and 3),
and the interactions between condition and community.
(Supplemental Appendix 1 at http://annfammed.org/
content/13/Suppl_1/S50/suppl/DC1.) We found a significant
interaction between communities and condition
(PLSP vs control) for age and significant differences by
condition for education and income. Accordingly, age,
education, and income were included as control variables
in all statistical evaluations.
