In addition, the authors make a lot of self-references, which shadows the fact that many of the used sub-models are adjustment taken from elsewhere and ideas from other sources.
When only the 3 most commonly used TKA models were analyzed, adjustment was also made for use of implant model.
The University HealthSystem Consortium UHCC) mortality risk adjustment models are increasingly being used as benchmarks for quality assessment.
Simulation analyses are required to determine under which condition such adjustment models are valid.
More refined neonatal risk adjustment models are currently under development for use with the PHIS database (personal communication Matt Hall, CHCA).
Thus, appropriate risk-adjustment models are desired.
The indexes of adjustments of models are presented according to Byrne (2011).
Models were examined with adjustment for BMI and waist circumference simultaneously and with adjustment for each separately.
Univariate logistic regression models were fit without adjustment.
Random intercept models were used for adjustment for physicians and practices.
Proportional hazard time-dependent covariate models were computed with adjustment for demographic characteristics, comorbidities, and laboratory variables.
