Bolded numbers on this “p” column represents “statistically significant.”
Categorical variables presented as counts and percent, while continuous variables were presented as mean and SD.
Continuous variables were presented as median and interquartile range, while there is non-normal distribution
p-Value test for association between KNF status and categorical risk factors is chi-square test, while p-value test for association between KNF status and continuous risk factors is using independent t-test. All are using 0.05 as significant level.
p-Value test for association between KNF status and continuous risk factors is using Mann–Whitney U test (Wilcoxon rank-sum test) while there is non-normal distribution. All use 0.05 as significance level.
SD, standard deviation; zBMI, BMI z-score.
