The construction procedure factors considered, in the study, were placing sequence, length of placement, and curing.
To assess variation in feeding practice at hospital discharge after the Norwood procedure, factors associated with tube feeding, and associations among site, feeding mode, and growth before stage II.
The effects of several main procedure factors (i.e., sulfide ion concentration, applied voltage, stirring rate and reactor temperature) on the particle size of synthesized nickel sulfide particles were investigated.
New methods are also needed to measure treatment (surgical procedure) factors.
Using a manual backwards stepwise selection procedure, factors with higher p-values were removed until only variables with a p-value <0.05 were left in the final model [ 17].
We performed all analyses in sas 9.1 (Procedures: FACTOR, MEANS, MIXED, REG, SAS Institute Inc., Cary, NC).
However, slight differences were observed in Finnish children [ 15], where the identified factors were 'fear of highly invasive dental procedures' (Factor 1), 'fear of potential victimization, strangers, choking, and hospital' (Factor 2), and 'fear of less invasive procedures' (Factor 3).
Four factors were extracted: Factor 1, 'fear of usual dental procedures'; Factor 2, 'fear of health care personnel and injections'; Factor 3, 'fear of strangers'; and Factor 4, 'fear of general medical aspects of treatment'.
The evaluation of the DCE involved descriptive methods (frequency tables, statistics of distribution), bivariate procedures (cross tables, comparisons of means, ANOVA), and complex multivariate procedures (factor analysis [PCA], probit models, logit models).
