Summary of the findings from the seven papers with interventions regarding diathermy, sample size, and the relative risk reduction for WOMAC pain subscale. H-PSWD (high-pulse short wave diathermy), L-PSWD (low-pulse short wave diathermy), MD (microwave diathermy), SWD (short-wave diathermy), SHT (superficial microwave diathermy), DHT (deep microwave diathermy), CSWD (continuous short-wave diathermy), and PSWD (pulsed short-wave diathermy).
