CB-induced effect on neutrophil influx depending on the retained surface area dose measured following 4-week or 6-week (square) and 13-week (circle) inhalation exposure. Details of the post-exposure times are provided in Supplemental 9. The grey line shows the fit of the regression model for 4-week Printex-90 exposure (from this work). The dotted grey lines delimit the 95% confidence interval of the regression model
