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

Autism spectrum disorder can be reliably diagnosed prior to age 2, and early, intensive intervention has been found to improve long-term outcomes. Nonetheless, most children with ASD do not receive a diagnosis until after age 3, with even later diagnoses for children from non-white ethnic groups. This study conducted telephone surveys with California Part C early intervention managers regarding policies and practices for early identification and intervention for ASD. Findings indicated that 85% of agencies conduct screening for ASD, but only 39% conduct ASD diagnostic assessments prior to age 3. Recommendations for policy changes to align Part C practices with best practice guidelines are provided.
