Example: "The researchers conducted analyses by adding the new variables to their existing data set."
Alternatives: "evaluations through the inclusion of" or "assessments by incorporating the".
After the initial analyses, sensitivity analyses were done by adding the stratifying variables (practice size, practice prescribing status, and country), age, duration of illness, and any symptoms found to be significantly associated in univariate analyses at the 10% level into each model as covariates.
The samples for the TEM analyses were prepared by adding the diluted sample to ethanol drop-wise on a 300-mesh carbon support copper grid (Ted Pella, Inc., Redding, CA, USA).
34 Subgroup analyses were performed by adding the interaction between these factors and treatment into the survival analysis model and by observing whether the change in the model log likelihood was statistically significant.
Subgroup analyses were done by adding the stratification variable to the mixed model both as a main fixed effect and interacting with the fixed effects of the separate examinations.
After another hour of incubation at room temperature and removal of unbound Streptavidin by washing, we analysed the plate by adding the substrate TMB (tetramethylbenzidine), resulting in a blue colour change.
The independent relationship of uPA system components with DSS and OS of ccRCC patients was evaluated by multivariate Cox's regression analyses by adding these factors separately to a base model consisting of clinicopathological parameters including gender, age, tumour stage and tumour grade.
These competing risk analyses can be provided by adding the 'cmprsk' package to R. Excellent instructions for the use of this package have been provided in this journal by Scrucca et al. in 2007 and 2010.
As in the prior analyses, we calculated cumulative exposure by adding the RDDs at each exposed residence.
