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

Using a newly developed Assessment of the Development of Russian Language (ORRIA), we investigated differences in language development between rural vs. urban Russian-speaking children (n = 100 with a mean age of 6.75) subdivided into groups with and without developmental language disorders. Using classical test theory and item response theory approaches, we found that while ORRIA displayed overall satisfactory psychometric properties, several of its items showed differential item functioning favoring rural children, and several others favoring urban children. After the removal of these items, rural children significantly underperformed on ORRIA compared to urban children. The urbanization factor did not significantly interact with language group. We discuss the latter finding in the context of the multiple additive risk factors for language development and emphasize the need for future studies of the mechanisms that underlie these influences and the implications of these findings for our understanding of the etiological architecture of children's language development.
