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

[Purpose] To test the effect of the hypoxia-inducible factor 1-alpha (HIF-1α) inhibitor, YC-1, on the upregulation of HIF-1α that leads to immobilization-induced muscle fibrosis underlying muscle contracture. [Materials and Methods] Rats were divided into control, immobilization (immobilization only), and YC-1 (immobilization and YC-1 injection) groups. The soleus muscles were the specimens. [Results] The HIF-1α protein expression in the control, immobilization, and YC-1 groups was 0.26 ± 0.11, 0.94 ± 0.28, and 0.66 ± 0.15, respectively. The expression of HIF-1α protein in the immobilization and YC-1 groups was significantly higher than in the control group and it was lower in the YC-1 group than in the immobilization group. There were strong positive correlations between HIF-1α protein expression and transforming growth factor (TGF)-β1 mRNA expression, TGF-β1 and α-smooth muscle actin (SMA) mRNA expressions, and between α-SMA mRNA expression and hydroxyproline content. A strong negative correlation was found between hydroxyproline content and range of motion on dorsiflexion at four-weeks. [Conclusion] Inhibition of HIF-1α may contribute to suppressing the overexpression of fibrosis-related molecules triggered by upregulation of HIF-1α, which may mitigate immobilization-induced muscle fibrosis related to muscle contracture.
