The N2 During Preschool: Temporal Stability and a Test of Bidirectional Effects With Maternal Emotion Characteristics in a White, European-American Sample.
Article in Child development. 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
Despite well-documented behavioral changes, the development of neuropsychological substrates underlying inhibitory control remains unknown, hindering understanding of this construct over time. Stability and change in N2, a neural correlate of inhibitory control, and its crosslagged, bidirectional associations with maternal emotion characteristics were examined in 121 preschoolers (59% female, predominantly White) between 2014 and 2017. N2 was stable from 3 to 5 years of age. Greater maternal negativity at age 4 predicted smaller N2 amplitudes in preschoolers at age 5 (β = 0.22); preschoolers' N2 amplitudes did not predict subsequent emotion characteristics in mothers. Findings provide initial evidence for mother-to-child, but not child-to-mother effects linking N2 with mothers' emotion characteristics and a foundation for future longitudinal work on developing neural correlates of inhibitory control in preschoolers.
