Associations with DailySteps are adjusted for age, gender, and BMI. Sphingolipids significant after FDR (false discovery rate) correction (q < 0.1) are highlighted in bold, whereas those that are also significantly associated with FBG levels are marked with an asterisk (*). The code to generate this table can be found in S2 Data.
Abbreviations: BMI, body mass index; Cer, ceramide; DailySteps, average daily steps; FBG, fasting blood glucose; FDR, false discovery rate; GlcCer, glucosylceramide; SM, sphingomyelin.
