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.

Abstract

backgroundMyofascial pain syndrome (MPS) is commonly seen in clinical settings and negatively influences a patient's daily life. Recently, the application of extracorporeal shock wave therapy (ESWT) has been utilized as one of the treatment methods for MPS. The aim of this systematic review and meta-analysis was to summarize the current evidence for the short-term effect of ESWT on MPS of trapezius.

methodsPubMed, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials were searched from the database inception to March 2019. Two reviewers independently screened articles, evaluated methodological quality, and extracted data. The primary outcome was post-interventional pain intensity.

resultsRandomized controlled trials (RCTs) were conducted to determine whether ESWT was used as the main treatment on MPS. The 5 studies reviewed in this meta-analysis were evaluated for changes in pain intensity. Compared with other treatments, focused ESWT in MPS was more effective in reducing the scores of visual analog scale (VAS) (standardized mean difference [SMD] = -0.48, 95% CI -0.74 to -0.22).

conclusionsThere is very low level evidence that focused ESWT is effective for short-term relief of neck pain in MPS. The limited sample size and poor quality of these studies highlight and support the need for large scale, good quality placebo controlled trials in this area.
