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

backgroundLong-term opioid treatment (L-TOT) may have consequences that are mediated by factors affecting functionality and health-related quality of life. This study aimed at investigating associations between L-TOT and clinical outcomes including sustained attention, short-term and working memory, worst pain intensity, sleep quality, mood, and health-related quality of life in patients with chronic non-cancer pain (CNCP). Additionally, the study aimed at exploring whether endocrine biomarkers mediate the relationship between L-TOT and these outcomes.

methodsCross-sectional study with 82 adult CNCP patients divided into two groups (opioid treated (n = 38) and controls not treated with opioids (n = 44)). Linear regression analyses assessed associations between L-TOT, outcome variables, and the mediating effects of endocrine biomarkers. A Bootstrap approach with 95% confidence intervals was applied to analyse the natural indirect effect.

resultsThe opioid group had worse sleep quality (p = 0.018), physical functioning (p = 0.0186), social functioning (p = 0.002), and higher pain intensity (p < 0.001) compared with controls. Men in the L-TOT group experienced worse measures for the same variables, and additionally for anxiety (p = 0.028), depression (p = 0.040), role physical (p = 0.038), role emotional (p < 0.001), fatigue (p = 0.019), and emotional well-being (p = 0.001). Only the association between L-TOT and anxiety in men was significantly mediated by total testosterone (β = 1.6, Bias-Corrected Bootstrap 95% CI: 0.1; 4.1, p = 0.045).

conclusionsCNCP patients in L-TOT showed significantly poorer outcomes than controls. Only testosterone mediated anxiety in men, indicating a natural indirect effect. Causality and mediating effects of endocrine biomarkers need to be further explored, but the associations are an alert to the potential effects of opioids. SIGNIFICANCE STATEMENT: This study reveals the broader health impacts of opioid use, particularly the role of hormone-related factors in men, which may be linked to specific adverse effects and consequences. Investigating these hormonal dynamics could lead to improved treatment strategies and outcomes.
