XML transcends the data-content dichotomy.
Phi correlation is a special case from the Pearson Product Moment correlation applied to data containing dichotomies [ 3] and is generated by the ordinary correlation formula generally used in factor analysis programs.
Correlation between the CD133 or p53 expression and clinicopathological parameters was conducted by use of Fisher's exact test or Chi-square test (for dichotomy data) and student's T test or linear regression analysis (for parametric data).
Analysis of the data reveals a dichotomy in the cooking activity choices made by the adults between baking recipes which required a high level of adult control, and other cooking activities which required minimal adult intervention.
Our data reveal a dichotomy of pro- and antitumorigenic action of senescent cells and their secretome.
Based on both independent and combined analysis of mitochondrial and nuclear sequence data the basal dichotomy within Crenadactylus was between a south/western clade (three major lineages) and a north/central clade (seven major lineages).
Using a logistic regression, after recording data into a dichotomy (zeros vs. ones) is a common approach, but important information is discarded since the question of "how much" something occurred is reduced to "whether or not" it occurred [ 30].
Antibody subclass data confirmed this dichotomy, with alum promoting an IgG1-dominated antibody response associated with Th2 induction, and CpG adjuvants boosting only IgG2a responses that are dependent on Th1-derived IFNγ (16, 19).
For correlations of the ESRD-SCL scales with demographic and clinical variable we used Spearman's rank correlations, because of the ordinal nature of some of the data and the dichotomy of some variables.
When all the included studies here are dichotomized into patient groups positive for endotoxemia (that is, groups one and three aggregated) versus negative (that is, groups two and four aggregated), there were only five studies for which a difference in mortality proportions of ≥20% was apparent in the dichotomy (data not shown) [ 5, 11, 12, 21, 24].
