From: Lung transcriptomic clock predicts premature aging in cigarette smoke-exposed mice
Smoking cessation and switching to HTPs reverse the accelerated transcriptomic aging. a. Chronological age versus predicted age for sham-, CS- and heated tobacco product-exposed mice as well as for cessation and switching groups. b. Boxplots of the residuals (predicted age minus chronological age) for the indicated groups. Significance levels for t-test are indicated for each comparison (**** P < 0.0001; *** P < 0.001; ** P < 0.01; * P < 0.05;. P < 0.1; ns P ≥ 0.1). The p-value from one-way ANOVA test comparing all the groups is indicated
