Validity and Reliability of a Language Development Scale for Persian-speaking Children Aged 2-6 Years.
Article in Iranian journal of medical sciences, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLanguage disorders may affect receptive and/or expressive language skills. The use of a validated and reliable assessment tool is essential to assess these skills in children. The present study aimed to develop a valid and reliable language development instrument for Persian-speaking children aged 2-6 years.
methodsThe present cross-sectional study was conducted during 2016-2017 in three main Iranian cities, namely Mashhad, Tehran, and Isfahan. The target population was children between the ages of 2 and 6 in various kindergartens and schools. The Persian Language Development Scale (PLDS) was developed by incorporating linguistic characteristics of the Persian language and Iranian culture. Following a number of iterations, including a pilot study of 36 children, the final version of the PLDS tool was used to assess the receptive and expressive language skills of 460 children. The reliability and validity of the PLDS tool were examined.
resultsThe content validity ratio (CRV) of the PLDS tool was 0.85. The tool could differentiate children by age, but not by sex. The test-retest reliability, with 10 days interval, showed a significant correlation between the coefficients of receptive (0.96) and expressive (0.93) scales. The intraclass correlation coefficient (ICC) for receptive and expressive scales was 0.93 and 0.98, respectively. The internal consistency, using the KR-21, for the receptive and expressive scales was 0.88 and 0.92, respectively.
conclusionA language development scale has been developed to assess receptive and expressive language skills in Iranian children aged 2-6 years. The validity and reliability of the tool were confirmed.
