Fig 4 shows mortality [median (IQR)] in the 2 normal fibroblast culture analysed.

<p>The mortality is shown for control cancer cells and for cells treated at increasing concentrations of Apixaban (0.1 μg/ml, 0,2 μg/ml, 0,5 μg/ml, 1 μg/ml, 5 μg/ml). The time points considered are: 24-h, 48-h, 72-h. 96-h. Mortality is expressed as Ncell/ml. At 96-h, for 5 μg/ml Apixaban, no statistically significant difference was observed between controls and both fibroblasts cultures (see text).
