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

backgroundOpioids as the strongest pain drugs are often used for chronic pain although their long-term efficacy has not yet been clarified. In this longitudinal study, we compared the pain sensitivity of patients with chronic low back pain (cLBP) under long-term opioid use and treated with multidisciplinary pain therapy.

methodsThe pain sensitivity was measured by the quantitative sensory testing (QST) technique at admission, discharge and 6 months after the beginning of the study in 34 patients with both cLBP and opioid medication, 33 opioid-naive cLBP patients and those neither with pain nor opioid use (HC). Both patient groups underwent a 3-week multidisciplinary pain therapy (MDPT).

resultsUnder opioid use, the patients showed significantly lower cold and heat pain thresholds compared to HC and delayed reaction to warm stimuli. After 3 weeks of MDPT, opioid-positive patients still had a lower pain threshold to cold and heat stimuli, while opioid-naive patients normalised their pain perception.

conclusionOur findings suggest that long-term use of opioids intensifies the peripheral sensitisation of cLBP. The MDPT can counteract this process.
