Past studies such as Ward et al. (2015) that have investigated multiple interacting factors including drought and nitrogen, observed greater reductions in transpiration in a combined treatment of fertilization and throughfall removal in Pinus taeda relative to the control and any single treatment (e.g., fertilization and throughfall removal).
Having investigated multiple permutation models, we chose a null distribution derived from genome-wide permutation (Methods S1).
Studies on the NHI had investigated multiple perspectives, including, for example, access, expenditure, and copayment, and demonstrated that the NHI had significant effects on the insured.
As few reports have investigated multiple time points and most natural history of CTCs remains elusive, the controversies on better time points for CTC detection have not been well understood biologically and pathologically.
Many epidemiologic studies have implicated individual dietary and lifestyle factors in the development of type 2 diabetes in diverse populations, yet few studies have investigated multiple risk factors simultaneously.
Since 2007, state and local health departments and the Centers for Disease Control and Prevention have investigated multiple salmonellosis outbreaks linked to meat purchased at live-bird markets (LBMs) and live-animal markets (LAMs), where poultry and livestock are sold for onsite slaughter.
So far, no study has investigated whether multiple infection can lead the establishment of infection depending on initial virus load.
The HMP has investigated the microorganisms from multiple locations on the human body, including the gastrointestinal tract, oral cavity, nasal passages, skin, and urogenital tract.
No large observational study has investigated the influence of multiple organ dysfunctions and old age on the dosage and duration of RF infusion in critically ill patients.
We do not expect there to be any single scale of interest in this middle-scale structure of the protein interaction network; although previous studies have applied community detection algorithms to protein interaction networks, no study to our knowledge has investigated this structure at multiple resolutions.
