<p>Legend: A Forest Plot showing odds ratio values and 95% confidence intervals for: (A) Model II—Pap cytology and mtDNA ancestry, adjusted by socio-demographic variables and, (B) Model III—Pap cytology and mtDNA haplogroups, adjusted by socio-demographic variables. The x-axis represents the odds ratio (circles and square) and 95% confidence intervals (whiskers). The dashed vertical line indicates an OR value of 1. Non-significant values are shown as a small circle. Significant values are shown as square, with the OR (CI95%) as a legend into the figure. Details on other OR (CI = 95%) and p values are provided in the Supplementary Information (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0190966#pone.0190966.s002" target="_blank">S2</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0190966#pone.0190966.s003" target="_blank">S3</a> Tables). Amerindian ancestry and haplogroup A were not plotted since they were used as reference values (OR = 1).</p
