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

purposeDegenerative cervical myelopathy (DCM) is the most common non-traumatic cause of spinal cord dysfunction. Prediction of the neurological outcome after surgery is important. The aim of this study was to analyze the relationship between first symptoms of DCM and the neurological outcome after surgery.

methodsA retrospective analysis over a period of 10 years was performed. First symptoms such as cervicobrachial neuralgia, sensory and motor deficits and gait disturbances were evaluated regarding the postoperative neurological outcome. The modified Japanese Orthopedic Association Score (mJOA Score) was used to evaluate neurological outcome.

resultsIn total, 411 patients (263 males, 64%) with a median age of 62.6 ± 12.1 years were included. Cervicobrachial neuralgia was described in 40.2%, gait disturbance in 31.6%, sensory deficits in 19% and motor deficits in 9.2% as first symptom. Patients with cervicobrachial neuralgia were significantly younger (median age of 58 years, p = 0.0005) than patients with gait disturbances (median age of 68 years, p = 0.0005). Patients with gait disturbances and motor deficits as first symptom showed significantly lower mJOA Scores than other patients (p = 0.0005). Additionally, motor deficits and gait disturbance were negative predictors for postoperative outcome according to the mJOA Score.

conclusionMotor deficits and gait disturbances as the first symptom of DCM are negative predictors for postoperative neurological outcome. Nevertheless, patients with motor deficits and gait disturbance significantly profit from the surgical treatment despite poor preoperative mJOA Score.
