Does Cognitive Functional Therapy Reduce the Amount of Opioids Dispensed for Chronic Low Back Pain Over 12 Months: A Secondary Analysis From the RESTORE Trial.
Observational study in European journal of pain (London, England), 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
backgroundGiven the potential harms associated with opioids, interventions that can safely and effectively reduce the persistent use of opioids are important. Biopsychosocial interventions including Cognitive Functional Therapy (CFT) are effective for reducing chronic low back pain (LBP) and associated disability; however, it is unclear if they are effective at reducing or preventing new opioid use. The aim of this study was to investigate whether CFT with or without biofeedback changed the amount of opioid dispensed over 12-months compared to usual care in people with chronic, non-specific LBP.
methodsThis study is a secondary analysis of the RESTORE trial (n = 492) which randomly allocated participants with chronic LBP to one of three groups (CFT only, CFT-plus-biofeedback; usual care). This analysis included 301 participants who consented to their Pharmaceutical Benefits Scheme data being used (CFT only n = 107; CFT-plus-biofeedback n = 106; usual care n = 88). The primary outcome was average morphine equivalent dose per day dispensed during each quarter in the first 12 months of the trial. The secondary outcome was the proportion of participants that had any opioids dispensed during each quarter.
resultsThere was only a small percentage of participants taking opioids and we did not find any statistically or clinically significant differences between the two CFT groups and the usual care group (p ≥ 0.140) for either outcome. Clinical improvements in pain and disability following a biopsychosocial intervention do not necessarily lead to a reduction in opioids dispensed. Interventions targeting opioid reduction may be required to reduce the use of opioids in this population. SIGNIFICANCE STATEMENT: There is growing evidence that Cognitive Functional Therapy (CFT) is effective for reducing chronic low back pain and associated disability; however, no previous trials have investigated if CFT is also effective at reducing opioid use. This randomised controlled trial found CFT was not effective in reducing opioid use in people with chronic low back pain, despite it having large effects on pain and activity limitation.
