Comparisons between the two groups were analyzed by independent samples t-test or Mann Whitney U test, and categorical data by chi-square test. Pearson or Spearman correlation analysis was used for the correlation between AL and SER. Using a multivariate linear model with analysis of covariance, ...

(MLR): Regress a categorical dependent variable with more than two categories on a set of independent variables. This procedure helps you accurately predict group membership within key groups. You can also use stepwise functionality, including forward entry, backw...
Statistical analyses were verified in their categorical variables by chi-square test and in their numerical variables with student’s t-test. Results were considered to be significant at p < 0.05. Cursor on image to zoom/Click text to open image ...
conducted using generalized estimating equations (GEEs) to account for correlated data from the same patients responding at each follow-up; normal distributions with identity link functions were used for continuous outcomes, and binomial distributions with logit link function were used for categorical ...
For descriptive analysis, we used proportions and ratios to summarise categorical data, and means, standard deviations for numerical data or medians and first/third quartiles for very skewed distributions of numerical variables. As a descriptive summary of mortality, we fitted an unadjusted and PIM2...
Note here that we have to do a bit of juggling; anything with a hits value of less than 1 is reported as “<1”, but as this is a string R then takeshitsto be a categorical variable rather than numerical variable. So we convert all instances of “<1” to 0 and explicitly tell R...
Comparative analysis was conducted with Student t-test or Mann-whithney test fro numerical variable and Chi-Square for categorical variables. Survival were compared and reported using Log rank test and Kaplan Meier methods. A Cox Proportional Hazard model was developed to identify risk factors for ...
Classical metabolomic and new metabolic network methods were used to study the developmental features of autism spectrum disorder (ASD) in newborns (n = 205) and 5-year-old children (n = 53). Eighty percent of the metabolic impact in ASD was
Nearest Neighbor analysis – Use for prediction (with a specified outcome) or for classification (with no outcome specified); specify the distance metric used to measure the similarity of cases; and control whether missing values or categorical variables are treate...
