Neurological impairment score in lumbar spinal stenosis.
Article in European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
BACKGROUND AND
aimThe Oswestry Disability Index (ODI) is an interview-based instrument generally accepted as a measure of disability in patients with lumbar spinal stenosis (LSS). There is, however, no generally accepted measure for neurological impairment in LSS. We therefore developed a scoring system [neurological impairment score in lumbar spinal stenosis (NIS-LSS)] for the assessment of neurological impairment in the lower limbs of patients with LSS, then performed a validation study to facilitate its implementation in the routine clinical evaluation of patients with LSS.
methodsThe NIS-LSS is based on the combined evaluation of tendon reflexes, tactile and vibratory sensation, pareses, and the ability to walk and run; the total score ranges from 0 (inability to walk) to 33 points (no impairment). A group of 117 patients with LSS and a control group of 63 age- and sex-matched healthy volunteers were assessed with the NIS-LSS to evaluate capacity to discriminate between LSS patients and controls. A correlation with the ODI was performed for assessment of construct validity.
resultsThe median NIS-LSS was 27 points in LSS patients compared with 33 points in controls. The NIS-LSS discriminated LSS patients from healthy controls to a high degree of significance: the optimum NIS-LSS cut-off value was 32 points with a sensitivity of 85.5% and a specificity of 81.3% (p < 0.001). Overall NIS-LSS correlated significantly with the ODI score (p < 0.001). Vibratory sensation (p = 0.04), presence of paresis (p = 0.01) and especially the ability to walk and run (p < 0.001) were the NIS-LSS elements that correlated most closely with the degree of disability assessed by the ODI.
conclusionsThe NIS-LSS is a simple and valid measure of neurological impairment in the lower limbs of patients with LSS (without comorbidity), discriminating them from healthy controls to a high degree of sensitivity and specificity and correlating closely with the degree of disability. It extends our ability to quantify neurological status and to follow changes arising out of the natural course of the disease or the effects of treatment.
