Table 4. Summary statistics stratified by demographic characteristics for the three- to five-year-old age group (A) and six- to eight-year-old age group (B).
The data are represented as s, mean PSC/VELO scores, Spearman's rank correlation coefficient between the VELO total score versus PSC total score and 95% confidence interval. The data are further stratified by age group and patient demographics.
s: survey pairs; x̄: mean; rs: Spearman's rank correlation coefficient; CI: confidence interval
Statistical significance (p ≤ 0.05) between means is denoted as superscripts:
*: significant difference between groups, A: significant difference when compared to patients who identify as Asian, B: significant difference when compared to patients who identify as Black, H: significant difference when compared to patients who identify as Hispanic, W: significant difference when compared to patients who identify as White, O: significant difference when compared to patients who identify as "Other"
Race and ethnicity documented as "Other" was not defined by the electronic medical record.
