Relationship between early neurological function and motor skills in Brazilian preterm infants: a cross-sectional study.
Article in BMC pediatrics, 2025. 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
backgroundPreterm infants have an increased risk of neurodevelopmental delays, with consequences that may persist in later life. Thus, monitoring their development is needed for early detection and targeted intervention. This study aimed to assess the correlation between neurological function and motor skills in preterm infants from 2 to 6 months of corrected age after hospital discharge in an outpatient follow-up program.
methodsThis cross-sectional study involved 50 preterm infants with a mean gestational age of 32.0 (± 2.8) weeks and a mean birth weight of 1645.2 (± 576.5) grams. Neurological function and motor development were assessed once between two to six months of corrected age by using the Hammersmith Infant Neurological Examination (HINE) and Alberta Infant Motor Scale (AIMS), respectively. Data on pregnancy, type of delivery, and birth were obtained using interviews with family and medical records. The Spearman correlation coefficient assessed the association between HINE and AIMS scores.
resultsA significant correlation was found between HINE categories and AIMS subscales: cranial nerve function versus prone (r = 0.55; p < 0.001); posture versus prone (r = 0.69; p < 0.001); posture versus sitting (r = 0.67; p < 0.001); posture versus standing (r = 0.63; p < 0.001); tone versus sitting (r = 0.51; p < 0.001); tone versus standing (r = 0.49; p < 0.001); and total HINE versus total AIMS (r = 0.77; p < 0.001).
conclusionsThe present study found strong correlation between neurological function and motor skills in preterm infants during the first months of life. Whilst the HINE and AIMS can complete each other, where there are limited resources the HINE may be appropriate to administer as a single assessment.
