Family Language, Preschool, and Reading Achievement: The Interplay Between Inequality in Opportunities and Outcomes.
Article in Developmental science, 2026. 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
This article examines preschool attendance and reading proficiency among students from families that do not speak the test language at home. Both indicators are key targets of the United Nations' Sustainable Development Goal 4, which aims to promote equity in education. We analyze gaps in reading achievement and preschool participation between students who speak the test language at home and those who do not. The study also considers how these gaps intersect with socioeconomic background, focusing on students who face both linguistic and economic barriers. Using data from the 15 education systems that participated in all progress in international reading literacy study (PIRLS) cycles, we assess how these gaps have developed over time. Our findings show that significant gaps persist in most educational systems and, in some cases, have even widened. These social inequalities are especially marked among students with low socioeconomic status. We further examine how preschool attendance relates to reading achievement in grade 4 and whether this relationship varies by language and socioeconomic background. The analysis reveals that preschool attendance is particularly beneficial for students from non-test-language and lower socioeconomic backgrounds-groups that are also less likely to have access to early education. Our findings highlight a paradox: the children who would benefit most from attending preschool are those least likely to have access to it. SUMMARY: Access to preschool for non-test-language students has stagnated, with a growing gap in access between families speaking the test language at home and those who do not. A persistent basic literacy gap exists between family language groups, especially among students from lower socioeconomic backgrounds. Preschool attendance improves basic literacy outcomes, especially for doubly disadvantaged students from non-test-language backgrounds and lower socioeconomic status. This presents a notable paradox: those who benefit the most from attending pre-primary education are also the ones that are least likely to attend.
