Similar associations of daytime napping with the risk of incident T2D were observed in several sensitivity analyses, including further removing participants with a high level of glucose (≥7.0 mmol/L), participants with a high level of HbA1c (≥48 mmol/mol [6.5%]), participants who developed T2D within 2 years of follow‐up or participants who took any anti‐inflammatory drugs or after adjusting for glucose levels, fasting time, HbA1c levels, or CRP levels (Supplementary Tables S3–S7 in Appendix S1). The gene discussed is CRP; the disease is type 2 diabetes mellitus.
