  • Results presented across all tendinopathies and individual tendinopathies.

  • Large effects: Effect sizes obtained from outcomes measuring: (1) Disability; (2) Pain on loading/activity; (3) Pain without further specification; (4) Function; and (5) Pain over a specified time. Small effects: Effect sizes obtained from outcomes measuring: (1) Quality of Life and (2) Physical functional capacity.

  • CrI, credible interval; VPC, variance partition coefficient.
