Study Arms:
- Erchonia MLS (Type: ACTIVE_COMPARATOR): The Erchonia® MLS contains 10 independent diodes, each emitting 17 milliwatts (mW), 635 nanometers (nm) of red laser light.
- Placebo Laser (Type: PLACEBO_COMPARATOR): The Placebo Laser has the same appearance as the Erchonia MLS but does not emit any therapeutic light.

Based on this trial design, predict the completion outcome and termination type (if applicable).
