Failed to understand "by any single agent" - what does it mean?

Does it mean "if noly calculated in any single factor"?

Context:

According to the Center for Disease Control and Prevention, tobacco accounts for the greatest number of preventable deaths worldwide by any single agent. Nicotine, the active ingredient of tobacco, activates receptors known as nAChRs and, remarkably , unlike most other drugs of abuse, it acts as a "pharmacological chaperone" to stabilize assembly of its receptors within the Endoplasmic Reticulum (ER) and increase their abundance at the cell surface (up-regulation). Up-regulation of nAChRs plays a major role in nicotine addiction and, possibly, in the decreased susceptibility of smokers to Parkinson's disease.
