Schematic representation of the correlation between the dose of NAs per 105 cells, ranging from low (from 0 to 1 µg/105 cells), medium (from 1 to 5 µg/105 cells), and high dose (from 5 to 20 µg/105 cells), and the cell density, ranging from low (from 0 to 1 × 104 cells/cm2), medium (from 1 to 5 × 104 cells/cm2), and high cell density (from 5 × 104 to 2.5 × 105 cells/cm2). The trend line (R2 = 0.79) represents the tendency of the data taken from articles (references [17, 19, 21, 69, 86, 110, 112, 113, 152, 153, 174,175,176, 178, 179, 187, 198, 201,202,203]), where the cell density (cells/cm2) and the dose (µg) are specified
