Fig. 4From: A Nano-QSTR model to predict nano-cytotoxicity: an approach using human lung cells dataOverview of experimental and predicted cell viability (%) by ET nano-QSTR model for training and test sets. (a) Scatter plot representing the experimental cell viability (%) as a function of the predicted cell viability (%). The straight line illustrates the perfect agreement between experimental and calculated values. The dashed lines represent the 95% prediction level. (b1) Scatter plot representing the predicted cell viability (%) as a function of the residuals; (b2) Frequency distribution of the predicted cell viability (%). The dashed lines represent the residuals that are between − 10 and 10Back to article page
