Table 1 Randomised LLLT-trials excluded for not meeting trial design criteria for diagnosis, blinding or specific endpoints.

From: A systematic review with procedural assessments and meta-analysis of Low Level Laser Therapy in lateral elbow tendinopathy (tennis elbow)

Study by first author Year Method score Laser wavelength Application technique Result Reason for exclusion
Mulcahy [40] 1995 5 904 Not stated No significant differences between active and placebo LLLT Does not satisfy control group criterion: Lacks sufficient patient numbers in placebo control group as only 3 patients had tendinopathy
Simunovic [41] 1998 3 830 Tendon + Trigger Points LLLT significantly better than placebo Does not satisfy criterion for specific endpoint and standard number of treatments: Only bilateral conditions were given placebo treatment, but data for this group were not presented
Vasseljen [42] 1992 5 904 Tendon Traditional physiotherapy significantly better than LLLT Does not satisfy blinding criterion: Neither therapist, patients or observers were blinded in the traditional physiotherapy group
