FIG. 2.

Statistically significant laser parameters: Bozkaya et al. (830 nm), Abohabib et al. (940 nm), ELsyad et al. (940 nm), Palled et al. (1064 nm). Box and whisker plot diagrams indicate inner points, outer points, mean markers, mean lines, and upper and lower quartile ranges for all reported PBM settings. Wavelengths (830–1064 nm), laser power (0.033–1.7 W), beam area/spot size (0.0028–2.83 cm²), treatment time per point (3–60 sec), treatment time per visit (60–360 sec), energy dose per point (0.3–102 J), energy dose per visit (2–102 J), fluence per point (7.07–3750 J/cm²), contact points per visit (1–20), and number of appointments (4–7).
