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

backgroundPain in the tendons or ligaments is extremely common, accounting for 30% of the causes of visiting general practitioners. Polydeoxyribonucleotide (PDRN) is emerging as a new treatment for musculoskeletal pain. However, the effects of PDRN in patients with tendon or ligament pain are unclear. Therefore, this study aimed to determine the impact of PDRN in patients with tendon or ligament pain through a meta-analysis.

methodsElectronic literature search of PubMed, Embase, SCOPUS, and Cochrane Library databases of all articles on PDRN treatment for patients with tendon or ligament pain published in the English language from inception until January 31, 2020. The search identified 262 citations.

resultsOne randomized controlled trial and 3 retrospective observational studies were included. Pain due to tendon or ligament disorders showed significant improvement after PDRN injection (standardized mean difference [SMD] = -1.43, 95% confidence interval [CI] = -1.80 to -1.06, P < .00001). In the subanalysis of patients with rotator cuff tendinopathy, rotator cuff tendinopathy-induced pain significantly improved (SMD = -2.34, 95% CI = -3.61 to -1.07, P = .0003) after PDRN injection. However, there was no difference in shoulder pain and disability index score and strength of shoulder abduction in patients with rotator cuff tendinopathy (shoulder pain and disability index score, SMD = 1.16, 95% CI = -1.20 to 3.52, P = .34; strength of shoulder abduction, SMD = 0.42, 95% CI = -0.03 to 0.88, P = .07).

conclusionEffective pain relief was achieved in patients with tendon or ligament disorders after PDRN injection. To more precisely determine this effect, a meta-analysis with a larger number of clinical trials is warranted.
