Note: Results (displayed as mean ± SD or n [%]); Overall p values reflect baseline differences by class membership, analyzed using two sample t‐tests for continuous variables or Chi‐Square tests for categorical variables; Statistically significant p values (p < 0.05) are indicated in bold.
Abbreviations: BMI, body mass index; FDR, false discovery rate.

Analyzed using Fisher's Exact test using a 3 × 2 table. To compare the proportion of Black participants between the two trajectory groups, Fisher's Exact test p value for the 2 × 2 table (Black vs. non‐Black) is < 0.01.
