From this group, we excluded the 860 women who were diagnosed at autopsy or by death certificate only, who had zero or invalid survival time (n = 152), or whose address at diagnosis could not be precisely geocoded to determine neighborhood Hispanic enclave (n = 708), resulting in 37,695 cases included in these analyses.
Women who were excluded from the analysis because of invalid fasting times did not differ from those included in the analysis in race/ethnicity category, PIR, parity, BMI, waist circumference, or CRP values.
