Early Nutrition is Associated With Global Motion Perception and V5 Function in 7-Year-Old Children Born Very Preterm.
Article in Human brain mapping, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The dorsal stream vulnerability hypothesis suggests that preterm birth may preferentially impair development of the dorsal visual pathway. We explored the effects of early nutrition on dorsal stream development in a well-characterized cohort of 7-year-old children born very preterm. The children had been admitted to a tertiary hospital neonatal intensive care unit either before (OldPro group) or after (NewPro group) a parenteral nutrition protocol change that was intended to increase protein intake and reduce fluid volume intake. We assessed dorsal stream function using the blood oxygen level-dependent (BOLD) response in V1 and V5 to coherent and incoherent random dot kinematograms (RDKs), quantified using functional magnetic resonance imaging. V1 and V5 regions of interest could be localized in 24 children (OldPro n = 11, NewPro n = 13). Motion coherence thresholds, a psychophysical measure of global motion perception, were also available for 22 of these children (OldPro n = 9, NewPro n = 13). The NewPro group demonstrated a higher V5 BOLD response to RDK stimuli (OldPro: mean = 0.5%, SD = 0.2%; NewPro: mean = 1.0%, SD = 0.6%) and exhibited lower (better) motion coherence thresholds (OldPro: median = 74.0%, IQR: 59.5%-81.2%; NewPro: median = 36.8%, IQR: 27.5%-44.5%), compared to the OldPro group. The V1 BOLD response did not differ between the groups. There was a significant association between V5 ΔBOLD (coherent minus incoherent stimulus BOLD response) and motion coherence threshold. Together, these findings suggest that early nutrition may influence dorsal stream development in children born very preterm.
