β Values are coefficients of linear regressions using generalized estimated equations associated with changes in the exhaustion score; positive numbers represent greater exhaustion and negative numbers represent less exhaustion.
↵* P < .05.
↵† P < .001.
CI, confidence interval; EHR, electronic health record; QIC, quasi-likelihood under the independence model criterion; Ref, reference category.
