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

objectiveTo investigate the effect of ultrasound in the treatment of osteoarthritis of the knee.

methodsEighty-seven out- and in-patients with osteoarthritis of the knee (15 men and 72 women) underwent ultrasonic therapy from February to October 2010. The patients were randomly assigned to an ultrasound group (Group A) and a placebo group (Group B). Group A was offered ultrasonic therapy while Group B underwent mock treatment. The visual analogue scale (VAS) and Lequesne scores of the two groups before and after treatment were compared. The data were analyzed by normal distribution, Student's t-test and the rank sum test. The means during and after treatment of the VAS and Lequesne efficacy index of the treatment group were calculated and plotted on a bar graph.

resultsSingle sample analysis of Groups A and B showed VAS efficacy index: mean = 0.3640, P= 0.000; Lequesne efficacy index, median = 0.3080, P= 0.000, and mean = 0.1000, P= 0.000; Lequesne efficacy index, mean = 0.0364, P= 0.024, respectively. Independent samples t test and rank sum test showed significant differences between the two groups, namely P= 0.000 for both the VAS and Lequesne curative effect indexes. The means of the VAS efficacy index of the treatment group increased during and after treatment. The means of the Lequesne efficacy index of the treatment group showed no apparent decrease by 28 days after treatment.

conclusionUltrasound treatment significantly alleviates joint symptoms, relieving joint swelling, increasing joint mobility and reducing inflammation, in osteoarthritis patients.
