Statistical analysis
Continuous data are presented as medians and interquartile ranges. Categorical data are presented as numbers and percentages. Statistical differences between samples were assessed using chi‐square, Fisher's exact test, Student's t‑test, or Mann–Whitney test as appropriate. Analyses were performed using SAS 9.4 (SAS Institute, Cary, NC) and GraphPad Prism 8.2.1 (GraphPad, San Diego, CA). Statistical tests for variables were performed using a two‐sided alpha value of 0.05 to denote a significant level.
