Review in Current rheumatology reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02246088 (Effect of Neuroscience Education on Subjects With Chronic Knee Pain Related to Osteoarthritis), which is not on this map.

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.

Abstract

Osteoarthritis (OA), low back pain (LBP), and fibromyalgia (FM) are common chronic pain disorders that occur frequently in the general population. They are a significant cause of dysfunction and disability. Why some of these chronic pain disorders remain localized to few body areas (OA and LBP), whereas others become widespread (FM) is unclear at this time. Genetic, environmental, and psychosocial factors likely play an important role. Although patients with OA, LBP, and FM frequently demonstrate abnormalities of muscles, ligaments, or joints, the severity of such changes is only poorly correlated with clinical pain. Importantly, many patients with these chronic pain disorders show signs of central sensitization and abnormal endogenous pain modulation. Nociceptive signaling is actively regulated by the central nervous system to allow adaptive responses after tissue injuries. Thus, abnormal processing of tonic peripheral tissue impulse input likely plays an important role in the pathogenesis of OA, LBP, or FM. Tonic and/or intense afferent nociceptive barrage can result in central sensitization that depends on facilitatory input from brainstem centers via descending pain pathways to the spinal cord. Abnormal endogenous control of these descending pathways can lead to excessive excitability of dorsal horn neurons of the spinal cord and pain. Ineffective endogenous pain control and central sensitization are important features of OA, LBP, and FM patients.
