a
Unadjusted results based on Pearson chi-square or Fisher's exact test as appropriate. See text for explanation on how variables were previously selected. All 461 non-chagasic patients were included in the analysis.
b
Adjusted results based on logistic regression, all listed variables included. See text for explanation on how variables were previously selected. Missing cases were 17 due to listwise deletion. 444 patients remained in the analysis, 50 with a stroke and 394 without a stroke.
CAD: Coronary artery disease.
