Graphical illustration of the accelerometer isotemporal analyses showing the association of the time spent in different intensities of physical and sedentarism activities with oocytes and embryos obtained after stimulation in our study group (N = 98). The interpretation of this model is that by a given value of MVPA and registered time, an increase in, for example, 1.5 h in light PA accumulated during the whole day (slow walking, slow biking, some houseworks, etc.) should be mirrored by a decrease in sedentary time (the only variable left out of the model), which in turn would result in the change in the dependent variable indicated by the unstandardized regression coefficient. In our study, the regression coefficient for oocytes and embryos of the described models were 1.8 (P = 0.03) and 1.2 (P = 0.03), respectively (these values were rounded to the closest entire number in the figure for simplicity)
