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

STUDY

designCross-sectional analysis of baseline data of a prospective cohort study.

objectivesTo determine the prevalence of ulnar neuropathy at the elbow (UNE) and identify risk factors associated with UNE in wheelchair-dependent individuals with paraplegia.

settingRegional outpatient spinal cord injury clinic in San Jose, CA, USA.

methodsWheelchair-dependent individuals with paraplegia completed a questionnaire documenting symptomatology and possible activities contributing to UNE, such as hooking over the wheelchair handle, prolonged elbow leaning, and repetitive elbow flexion. Nerve conduction studies (NCS) of the median and ulnar nerves of the bilateral upper limbs were obtained. UNE was defined based on the motor NCS with an above-elbow to below-elbow segment conduction velocity slowing greater than 10 m/s than the below-elbow to wrist segment conduction velocity.

resultsThe prevalence of UNE in wheelchair-dependent individuals with paraplegia was 16% (8/49). Frequent hooking over the wheelchair handle (p = 0.05) and frequent elbow bending during transfers or weight shifts (p = 0.04) were associated with UNE. UNE was not significantly associated with age, time since spinal cord injury, or presence of pain and/or paresthesia in the ulnar nerve distribution.

conclusionsTransfers or weight shifts that involve hooking or repetitive elbow flexion may be modifiable risk factors for UNE specific to wheelchair-dependent individuals with paraplegia.
