Table 4

Predictors of longitudinal log-transformed RDW derived from a linear mixed-effects regression model.

Variable	Coefficient	Standardized error	95% CI	value
Intercept	14.0871	0.0512	13.9868-14.1874	<0.0001
Time	0.1132	0.0033	0.1066-0.1197	<0.0001
	1.0052	0.1081	0.7933-1.2170	<0.0001

CI: confidence interval; intercept: the mean of log-transformed RDW count at and ; time: the mean of the increasing of log-transformed RDW count at over time(daily); : the average increasing in log-transformed RDW count daily under the condition of the group of compared with the group of .
