Abbreviations: DHQ, Diet History Questionnaire; FFQ, Food Frequency Questionnaire; ICD-10, International Classification of Diseases, 10th revision; NCI, National Cancer Institute; NMIBC, non-muscle invasive bladder cancer.
The type of diet questionnaire differed by study phase. Harvard FFQ was administered July 1998 to December 2001 and NCI DHQ was administered January 2002 to July 2004.
Follow-up time is defined as years between bladder cancer diagnosis and date of death or December 31, 2017, whichever comes first.
Percentages are among those with an observed death. May not sum to 100% because of rounding.
ICD-10 codes that define cause of death are as follows: bladder cancer C67.9, non-bladder malignancy C00-C66 and C68-C96, cardiovascular disease I00-I99, respiratory system disease J00-J99. Other includes ICD codes not specified above and includes 3 participants missing cause of death.
