Similar to males, year was a significant predictor with an increasing trend in female mean breakage as the only predictor (linear mixed effect model: y = -0.8397 + 0.0009year, p year = 0.0007, conditional R 2 = 0.324, marginal R 2 = 0.006) and became marginally significant when age was added to the model (linear mixed effect model: y = -0.0019 + 0.0005year + 0.0049age, p year = 0.065, p age < 0.0001, conditional R 2 = 0.358, marginal R 2 = 0.066).
