The structural variables were generally stronger than any of the confounding variables, other than baseline eGFR.
All further modeling included the confounding variables.
The confounding variables showed no statistical significance in the results.
We assessed multicollinearity by investigating associations among the confounding variables.
The statistical methods were in general appropriate; however, the confounding variables were not measured in several studies and, as can be seen, the studies did not describe how they addressed missing data (items 6a and 6b).
To try and address this confounding variable, we next examined the risk of infertility in our stage I NSGCT patients who had been placed on surveillance and had never required chemotherapy (Table 5 >).
So we get rid of the confounding variable of immigration and we get the same results.
If the confounding criteria were met, then the confounding variable was forced back into the model.
The severity of protein-energy malnutrition was related significantly to the occurrence of bilateral infection, to an incomplete immunization scheme and poor socioeconomic status, however this study did not address the confounding between these variables.
The fact that the data in living human children parallels findings in rodents, and that the rodent experiments directly address potential confounding variables (e.g., predisposing genetic factors, nutrition differences, general environmental stimulation, health) militates against alternative hypotheses.
A more detailed set of instructions was created to address potential confounding variables, such as the interpretation of marrow FDG uptake, that required further clarification based on the reviewers' experience.
