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

The goal of the present study was to test theories about the extent to which individual differences in word reading align with those in spelling and the extent to which other cognitive and linguistic skills play different roles in word reading and spelling. Using data from 1,116 children ranging from 8 to 17 years, we modeled word reading and spelling as latent traits with two measures of each skill to reduce measurement error. The models also included five skills that have been theorized to relate differentially to reading and spelling: phonemic awareness, working memory, rapid automatized naming, arithmetic, and vocabulary. The latent-trait correlation for reading and spelling was very high, 0.96, although significantly less than perfect. Vocabulary correlated more strongly with reading (0.64) than spelling (0.56), but the correlations of the other skills with reading and spelling did not differ significantly. Breaking down the sample by age, we found a significantly higher latent-trait correlation between reading and spelling in the younger half (
