Viability was analyzed through the exposition of both lung cells (pulmonary epithelium) and blood vessels (vascular endothelium) to the vapor of e-liquid.
To give a meaning to the obtained results, two controls were included:
- cells that were not exposed to vapor, indicated in the chart as ‘Control’;
- cells treated with the vapor of Traditional Base, thus a product without the aromatic component.
The values are expressed as a percentage of the Control. Therefore, the Control will assume the value of 100% while the value the Sample can assume can be higher than, less than or equal to the Control.
According to the communication policy defined in partnerships with the research team all the values exceeding 100% have been cut to 100% for major clarity.
TRUSTiCERT endorses only the products that result values above 70%.
