Figure 8From: Tool to visualize and evaluate operator proficiency in laser hair-removal treatments Differences in indices among performance groups. Each performance group was characterized by using a combination of indices (*P < 0.05, **P < 0.01). The quantitative description of satisfactory patterns in laser delivery in LHR treatment aims to achieve minimal randomness in the spatial distribution of laser spots, with accurate estimation of the size of the laser spots.Back to article page
