Validation of a translated version of the modified Japanese Orthopedic Association (mJOA) cervical myelopathy score in an Arabic speaking population.

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
introductionDegenerative Cervical Myelopathy (DCM) is a growing disorder. Standardization of its assessment tools is an integral part of its management. The modified Japanese orthopedic association (mJOA) score is one of the most commonly used tools. Currently, there is no available Arabic translated version of any cervical myelopathy functional score. This study aimed to translate, culturally adapt, and measure the psychometric properties of an Arabic translated version of the mJOA.
methodsAfter translation of the score using the standard forward-backward translation procedure, a validation study including 100 patients was carried out from June 2019 to June 2020. The following psychometric properties were measured: feasibility, reliability, internal consistency, validity, minimal clinically important difference (MCID), ceiling, and floor effect.
resultsNo problems were encountered during the process of translation and cross-cultural adaptation of the score. The mJOA-AR was found to be a feasible score. It showed high inter-observer reliability (r = 0.833, P < 0.001), test-retest reliability (r = 0.987, P < 0.001) and good internal consistency using Cronbach's alpha (0.777) and Pearson interclass correlation coefficient (r = 0.717). The score showed good convergent and divergent construct validity correlating it to the Arabic validated version of the neck disability index (NDI). The mJOA-AR had an MCID of 1.506. Both the ceiling and floor effects of the total score and the first and second domains were within the acceptable range, while the third and fourth domains had a high ceiling effect (30% and 39%, respectively). DISCUSSION: Our translated version of the mJOA score was found to be a feasible score with acceptable psychometric properties. This score can be utilized as a good outcome measure tool in Arabic-speaking countries.
