Figure 6: Decrease of postoperative pain during irradiation in the group with water-filtered infrared-A (wIRA) and visible light (VIS) and in the control group with only visible light (VIS) (Study Heidelberg)

(assessed with a visual analogue scale; given as minimum, percentiles of 25, median, percentiles of 75, and maximum (box and whiskers graph with the box representing the interquartile range), from [2], adapted from [19]).
During 230 single irradiations with wIRA(+VIS) the pain decreased without any exceptions, while pain remained unchanged in the control group (p<0.000001 for any single documented day as well as for all the days).
