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
backgroundCorticosteroid receptors, including mineralocorticoid receptor (MR) and glucocorticoid receptor (GR), play important roles in inflammatory pain in the dorsal root ganglion (DRG). Although it is widely known that activating the GR reduces inflammatory pain, it has recently been shown that MR activation contributes to pain and neuronal excitability in rodent studies. Moreover, little is known about the translation of this work to humans, or the mechanisms through which corticosteroid receptors regulate inflammatory pain.
methodsCorticosteroid receptor expression in human and mouse DRGs was characterized. RNAscope was used to perform high-resolution in situ hybridization for GR and MR mRNAs and to examine their colocalization with markers for nociceptors ( SCN10A , Na V 1.8 mRNA) and Aβ mechanoreceptors ( KCNS1 , Kv9.1 mRNA) in human DRG and C57BL/6J mouse DRG samples.
resultsGR and MR mRNAs are expressed in almost all DRG neurons across species. The 2 receptors colocalize in 99.2% of human DRG neurons and 95.9% of mouse DRG neurons ( P = .0004, Fisher exact test). In both human and mouse DRGs, the large-diameter KCNS1+ Aβ mechanoreceptors showed a significantly higher MR/GR ratio (MR-leaning) compared to KCNS1- neurons (human: 0.23 vs 0.04, P = .0002; mouse: 0.35 vs -0.24, P < .0001; log ratios, unpaired t test), whereas small-diameter SCN10A+ nociceptive neurons showed a significantly lower MR/GR ratio (GR-leaning) compared to SCN10A- neurons (human: -0.02 vs 0.18, P = .0001; mouse: -0.16 vs 0.08, P < .0001; log ratios, unpaired t test).
conclusionsThese findings indicate that mouse corticosteroid receptor mRNA expression reflects human expression in the DRG, and that mice could be a suitable model for studying corticosteroid receptor involvement in pain. Additionally, this study supports the translatability of rodent data to humans for the use of more selective corticosteroids at the DRG in pain treatments.
