1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The aim of this study was to evaluate if pulsed electromagnetic field therapy (PEMF) has additional effect on the classical physical treatment of knee osteoarthritis (OA) composed of hot pack, therapeutic ultrasound, and terminal isometric exercises. Forty patients (29 women and 11 men), ages 44 to 78 (mean age was 61.3 +/- 7.8 years) were included in our study. Patients with knee osteoarthritis [Kellgren-Lawrence criteria grade 2 and above and an average pain intensity of 40 or more on a 100-mm visual analog scale (VAS)] recruited from outpatient physical medicine and rehabilitation clinic were randomly assigned to receive PEMF or sham PEMF treatment in addition to their physical therapy. Both the PEMF and sham PEMF treatments being evaluated were 55 min/session, five sessions per week for 2 weeks. Each session comprise 20-min hot pack, 5-min therapeutic ultrasound, and 30-min PEMF or sham PEMF treatment applied to the knee of the patients. Patients were evaluated by the Western Ontario and McMasters Universities Osteoarthritis (WOMAC) Index and VAS at the baseline and at the end of treatment. Both PEMF and sham PEMF treatment groups showed statistically significant improvement in WOMAC pain and functional scores at the end of treatment (p < 0.001 in both groups). There were no statistically significant differences between groups in WOMAC pain, stiffness, and physical function scores after treatment (p = 0.906, p = 0.855, p = 0.809, respectively). There was neither difference in concomitant used acetaminophen dose in both groups (p = 0.289). The results of this study show that PEMF does not have additional effect on the classical physical treatment in reducing symptoms of knee OA.
