Variations in glucose, triglyceride and TyG index across the menstrual cycle for each model. Fat mass %, muscle mass %, age-specific grip strength (kg) z-score and age-specific cardiorespiratory fitness (METs) level z-score are categorised as quartiles. Physical activity (METs) is categorised into low, medium and high according to previously defined criteria. Curves represent GAM estimates using a smoothing spline function. Shaded areas represent 95% confidence intervals. The menstrual cycle phase is shown on a scale of 0–1 corresponding to the approximate phases: follicular phase, 0–0.54; luteal phase, 0.54–1 [38]. Analyses were adjusted for age, ethnicity and deprivation. Significant model fit for each sub-group is denoted by the respective number at the top right corner. TyG index, triglyceride to glucose index
