Objectives: To investigate the efficacy of non-surgical and non-interventional treatments for adults with low back pain compared with placebo. Eligibility criteria: Randomised controlled trials evaluating non-surgical and non-interventional treatments compared with placebo or sham in adults (≥18 years) reporting non-specific low back pain. Information sources: MEDLINE, CINAHL, EMBASE, PsychInfo and Cochrane Central Register of Controlled Trials were searched from inception to 14 April 2023. Results: A total of 301 trials (377 comparisons) provided data on 56 different treatments or treatment combinations. One treatment for acute low back pain (non-steroidal anti-inflammatory drugs (NSAIDs)), and five treatments for chronic low back pain (exercise, spinal manipulative therapy, taping, antidepressants, transient receptor potential vanilloid 1 (TRPV1) agonists) were efficacious; effect sizes were small and of moderate certainty. Three treatments for acute low back pain (exercise, glucocorticoid injections, paracetamol), and two treatments for chronic low back pain (antibiotics, anaesthetics) were not efficacious and are unlikely to be suitable treatment options; moderate certainty evidence. Evidence is inconclusive for remaining treatments due to small samples, imprecision, or low and very low certainty evidence. Conclusions: The current evidence shows that one in 10 non-surgical and non-interventional treatments for low back pain are efficacious, providing only small analgesic effects beyond placebo. The efficacy for the majority of treatments is uncertain due to the limited number of randomised participants and poor study quality. Further high-quality, placebo-controlled trials are warranted to address the remaining uncertainty in treatment efficacy along with greater consideration for placebo-control design of non-surgical and non-interventional treatments.
