Grammar in Boys With Idiopathic Autism Spectrum Disorder and Boys With Fragile X Syndrome Plus Autism Spectrum Disorder.

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
Purpose: Some boys with autism spectrum disorder (ASD) and boys with fragile X syndrome and a codiagnosis of ASD (FXS+ASD) have impairments in expressive grammatical abilities. The current study compared grammatical performance in these 2 groups of school-age boys. Method: Thirty-seven boys similar on mean length of utterance participated in the current study (FXS: n = 19, ASD: n = 18). Participants completed an ASD assessment, nonverbal IQ testing, and conversation language samples. Convergent validity of a sentence imitation task with a norm-referenced assessment of grammar was examined in addition to divergent validity of the measures with nonverbal IQ and vocabulary comprehension and production. Results: The boys with ASD outperformed the boys with FXS+ASD on the norm-referenced assessment of "be," and effect sizes indicate that the boys with ASD had better performance on past tense probes on the sentence imitation task and "do" on the norm-referenced assessment. The two measures of grammar had good convergent validity except for copula and auxiliary "be" and "do." Grammatical performance was not correlated with nonverbal IQ, and trends indicate a relationship between vocabulary and grammar. Conclusions: Despite being similar on mean length of utterance, there were group differences on grammatical performance. The sentence imitation task had good convergent validity with a norm-referenced assessment of grammar for the third-person singular and past tense probes and therefore could be an inexpensive and valid tool to use clinically for these populations. Future research should continue to refine this task, particularly for the probes with high rates of unscorable responses (i.e., "be" and "do").
