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

backgroundCervical intervertebral disc herniation can lead to myelopathy. Aging is an established variable related to spondylotic myelopathy. Studying this association will help in controlling the increase in spondylotic myelopathy with age.

objectivesTo study the association between cervical disc level, its direction, and the frequency of my-elopathy with age, and to assess the epidemiology of age-related cervical disc herniation and myelopathy.

designRetrospective review of magnetic resonance (MR) images.

settingTertiary referral hospital. PATIENTS AND

methodsWe studied the MR images of adults patients ( > 18 years of age) referred to our department between 2001 and 2012 for suspected cervical spondylopathy. The direction and severity of herniation and the presence of myelopathy was determined for spinal levels C2 to C7. MAIN OUTCOME MEASURE(S): Relationship between age-related cervical disc herniation and myelopathy.

resultsWe studied 6584 patient MR images, which included 2402 males (39.1%) and 3737 females (60.9%). The frequency of myelopathy increased with age from 0.6% in patients < 20 years of age, reaching 9.1% in patients > 70 years of age. The most common level affected by myelopathy was C5-C6. In elderly patients ( > 60 years), the C3-C4 level became the predominant level affected by myelopathy. Likewise, the frequency of central disc herniation increased significantly (P < .001) with age at all cervical levels. Furthermore, upper cervical levels showed a higher frequency of central disc herniation than lower cervical levels in the elderly.

conclusionThe increased frequency of central disc herniation with age suggest an important, and probably a cause-effect relationship, between herniation and myelopathy. LIMITATIONS: We were unable to access clinical data or electrophysiological studies to correlate with MR image findings.
