These associations included one trait in colony cells and three traits in isolate cells. We did not observe any inflation in association statistics for these traits (Lambda (λ) = 1.01 for the association in colony cells and λ = 1.01, 0.96, 0.98 for the associations in isolate cells) ...
where randomization evens out the distribution of confounding variables among groups, effectively cancelling out any bias that may exist in the data, and helping to ensure that any effects we see can be attributed to the treatment conditions in the study.Answer...
Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene have been recognized as genetic risk factors for Parkinson’s disease (PD). However, compared to cancer, fewer genetic mutations contribute to the cause of PD, propelling the search for protein b
The prognostic power of the profiles was found to be independent of confounding by known major clinicopathologic prognostic factors. For example, as above, the 5-miRNA profile was significantly prognostic of RFS when stratified by the presence of metastasis at diagnosis (no metastasis: median RFS 20...
(Fig.2aandd). To focus on products other than fixed carbon that influence heterotrophic viability and eliminate the confounding factor that cyanobacteria only generate sucrose in the light [12], co-cultures were supplemented with exogenous sucrose (2%) and cultivated in the light or dark. After ...
