We accounted for known strong predictors of cognitive function.
Because of the known strong effects of tracheostomy on swallowing function and a potential interaction between tracheostomy and duration of mechanical ventilation in the models we used to examine the effect of the duration of mechanical ventilation on the presence of dysphagia, we prespecified that we would perform separate multivariate analyses for patients with or without tracheostomy.
Dexamethasone was chosen as a representative of the glucocorticosteroids, because of its known strong anti-inflammatory properties.
Methylene blue was chosen in this study because of its known strong adsorption onto solids and its recognized usefulness in characterizing adsorptive material [27].
Using the expectation-maximization (EM) algorithm in SAS Genetics SAS Institutee, Cary, NC), common HLA class I B-C haplotypes were assigned for HLA-B and HLA-C alleles because of their known, strong linkage disequilibrium (LD) in the study population [30].
Despite non significance in the bivariate analyses, gender and SES were included in the multivariable analyses because of their known strong association with both mental health problems and sickness absence.
Despite individual CNTs being considered as one of the most known strong materials, much less is known about other CNT forms, such as CNT arrays, in terms of their mechanical performance (integrity).
Third, we lacked information on important factors such as gastroesophageal reflux disease and Helicobacter pylori infection status among participants, both of which are known strong risk factors for esophageal and gastric cancer.
Finally, and very importantly, we have not adjusted for the potential effects of education which is a known strong predictor of cognitive function [ 65– 67] and on the rates of decline [ 68].
The authors of this previous study suggested that the positive effect of ketorolac might be associated with an inhibitory effect on the perioperative production of prostaglandin, which is a known strong inhibitor of anticancer immunity (Table 3).
