The concerted actions of microRNA-29a and interferon-β modulate complete Freund's adjuvant-induced inflammatory pain by regulating the expression of type 1 interferon receptor, interferon-stimulated gene 15, and p-extracellular signal-regulated kinase.

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.
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
Background: Previous research has shown that type 1 interferons (IFN), such as IFN-α and IFN-ß, possess antiviral and antinociception effects. Elevated levels of microRNA-29a (miR-29a) have been observed during inflammatory pain, and as miR-29a targets the type 1 IFN receptor (IFNR1), our study aimed to investigate the involvement of miR-29a, type 1 IFN, and IFNR1 in inflammatory pain. Methods: Inflammatory pain was induced in male rats using complete Freund's adjuvant (CFA). The changes in miR-29a, IFN-ß, and IFNR1 were measured on Days 2, 3, 5, 7, and 10 post-CFA injection and expression of IFNR1, phospho-ERK (phosphorylated extracellular signal-regulated kinase) (p-ERK), extracellular signal-regulated kinase (ERK), and IFN-stimulated gene 15 (ISG15) were measured in rats that received an miR-29a inhibitor or miR-29a mimic. Results: Our results demonstrated elevated miR-29a expression (CFA 3 days: mean difference [95% confidence interval, CI]: 0.860 [0.657-1.062]; CFA 5 days: mean difference [95% CI]: 1.120 [0.917-1.322], Conclusions: Inhibiting miR-29a expression attenuates inflammatory pain by modulating IFNR1, ISG15, and p-ERK expression, highlighting the interactive roles of miR-29a and IFN-ß in the regulation of inflammatory pain.
