Other related information

Hemoglobin level was measured more than one time every year and at final follow-up in each individual.
For each patient, a linear regression model of time on hemoglobin was created, and the slope of the regression line was used to estimate the patient's changes in hemoglobin over time. Multivariable linear regression analyses were employed to explore the independent associations of annual hemoglobin decline with baseline clinical and histopathological covariates.
