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 histological and genetic changes associated with significant tendon-to-bone differences after extracorporeal shockwave therapy (ESWT) remain unknown. This controlled laboratory study investigated the histological and genetic changes induced by ESWT in the rotator cuff. Left supraspinatus tendon ruptures were induced in 22 retired male Wistar rats. Three weeks later, rotator cuff repair was performed. One week post-repair, the rats were randomly assigned into either the ESWT or control group, with 11 rats per group. Compared with the control group, the ratio of cellularity was significantly lower, while that of collagen fiber orientation was significantly higher in the ESWT group. The number of blood vessels and the total histological scores were not significantly different between the two groups. Real-time polymerase chain reaction analysis revealed significantly higher messenger RNA (mRNA) expressions of CCN2 and SCX in the ESWT group than in the control group. No statistically significant differences in mRNA expression were found between the SOX9 and Tnmd. ESWT induces histological changes and increases the mRNA expressions of CCN2 and SCX in the repair of chronic rotator cuff tears in rats. These findings highlight the potential of ESWT to promote histological and molecular changes associated with tendon-to-bone healing.
