Circulating microRNA expression underlying the association of opioid use with low bone mineral density.
Article in JBMR plus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Opioid drugs, prescribed for pain management or opioid use disorder, have been associated with decreased BMD and increased fracture risk. Changes in circulating microRNA (miRNA) levels have been observed in opioid-treated patients, and miRNAs are crucial regulators of bone metabolism, but the effects of circulating miRNAs on BMD in the context of opioid use remains unexplored. This study aims to identify circulating miRNAs differentially expressed with opioid use that may explain opioid use effects on BMD. We conducted a cross-sectional analysis of 5692 participants from the Framingham Heart Study Offspring and Third Generation cohorts for which 412 miRNA profiles were obtained via qRT-PCR. BMD measurements were obtained using DXA for most participants, among whom opioid use was reported in 62 (1.1%). We modeled miRNA as a function of opioid use and/or BMD, adjusting for age, sex, and BMI, in linear or logistic regression models. Significant miRNAs associated with both opioid use and BMD were then analyzed using a novel strategy for pathway enrichment to identify biological functions impacted by these miRNAs. We found a significant inverse association between opioid use and BMD after adjusting for covariates (β = -.042, 95% CI = -0.075, -0.007,
