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

objectiveThe association between birth weight and infants' neurodevelopment is not well understood. We aimed to examine the impact of birth weight on neurodevelopment of infants at age 1-6 months using data from the Wuhan Healthy Baby Cohort (WHBC) study. SETTING AND

participantsThis is a prospective cohort study of 4026 infants from the WHBC study who were born at the Women and Children's Hospital of Wuhan, China between October 2012 and September 2013 and who had complete healthcare records within 6 months after birth. Participants were categorised into three groups according to their birth weight: low birth weight (LBW; birth weight <2500 g), normal birth weight (2500 g ≤ birth weight <4000 g) and macrosomia (birth weight ≥4000 g).

main outcome measuresThe main outcomes were development quotient (DQ) and clinical diagnosis of neurodevelopmental delay. Both adjusted regression coefficients and ORs were estimated for LBW and macrosomia.

resultsOf the 4026 infants, 166 (4.12%) were of LBW and 237 (5.89%) were with macrosomia. Adjusted regression coefficients of LBW and macrosomia for gross motor DQ were -11.18 (95% CI -11.36 to 10.99) and 0.49 (95% CI 0.36 to 0.63), fine motor DQ -6.57 (95% CI -6.76 to -6.39) and -2.73 (95% CI -2.87 to -2.59), adaptability DQ -4.87 (95% CI -5.05 to -4.68) and -1.19 (95% CI -1.33 to -1.05), language DQ -6.23 (95% CI -6.42 to -6.05) and 0.43 (95% CI 0.29 to 0.57), and social behaviour DQ -6.82 (95% CI -7.01 to -6.64) and 1.10 (95% CI 0.96 to 1.24). Adjusted OR of LBW for clinical diagnosis of 'neurodevelopmental delay' in gross motor was 2.43 (95% CI 1.65 to 3.60), fine motor 1.49 (95% CI 1.01 to 2.19) and adaptability 1.56 (95% CI 1.06 to 2.31). LBW has no significant effects on 'neurodevelopmental delay' in language and social behaviour, and macrosomia has no significant effects on clinical diagnosis of 'neurodevelopmental delay' in all domains.

conclusionBoth LBW and macrosomia are associated with infants' DQ, and LBW increases the risk of being diagnosed with 'neurodevelopmental delay' in gross motor, fine motor and adaptability among infants aged 1-6 months.
