Question: Define extraneous variable and confounding variable. Describe two methods used to prevent extraneous variables from becoming confounding variables. Variable: Variables refer to something such as a per
After controlling for potential confounding variables such as age, sex, American Society of Anesthesiologist score, intravenous TXA (IV TXA) use, and preoperative Hgb, we found that patients with lower preoperative Hgb (g/dL per 1-unit decrease, odds ratio [OR], 2.6; 95% CI, 2.0-3.5; p ...
respectively, which passed this threshold (TableS6). One of the strongest associations in our suggestive results was between the distribution in size of RNA particles in the cytoplasm (Cytoplasm_Granularity_3_RNA) and rare
We use randomization in our selection process and the assignment of groups to reduce bias in our research studies. Biasness results from the introduction of unevenly distributed confounding variables, where randomization evens out the distribution of confounding variables among groups, effectively cancel...

The restrictive target list was too small (<5 targets) for many of the miRNAs but still produced some significant results for miRNAs with enough gene targets included in the analysis. To further test for the possibility of random association due to the multitude of variables, we generated 10 ...
