Heatmap depicting changes in outcome measures after PBM treatment, compared to enrolment: A after 12 weeks of PBM treatment in a clinic setting; B after 37 or 52 weeks of PBM treatment (clinic-treatment + self-administered home-treatment); C after 14 weeks of waitlist with no treatment. The columns are individual participants. The rows are assessed outcome measures. Shades of grey represent improvements in outcome measure; no colour represents no change in outcome measure; hatched represents a decline in an outcome measure; a diagonal bar represents no data for the outcome measure
