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

introductionChildren born extremely preterm (EP; <28 weeks' gestation) and/or extremely low birth weight (ELBW; <1000 g) are at increased risk of difficulties across a range of neurodevelopmental domains and respiratory outcomes long term. The Victorian Infant Collaborative Study (VICS) in Australia has tracked detailed perinatal and developmental outcomes across four distinct EP/ELBW birth cohorts: 1991-1992, 1997, 2005 and 2016-2017. Improvements in 2-year developmental outcomes were reported in the VICS 2016-2017 cohort compared with previous eras; however, whether these improvements are sustained to school-age is not known. The aim of the follow-up study is to assess neurodevelopmental and respiratory outcomes at school-age in the VICS 2016-2017 cohort and examine the effect of EP/ELBW birth on school-age functioning across the VICS epochs. METHODS AND ANALYSIS: This is a follow-up of the VICS 2016-2017 cohort, a prospective longitudinal cohort study of children born EP/ELBW and a contemporaneous group of term-born controls born in the state of Victoria, Australia. Children were previously assessed at 2 years' corrected age.Follow-up at 8-9 years' corrected age includes a comprehensive assessment of cognitive, motor, social and behavioural development and lung function.Follow-up at 8-9 years' corrected age includes a comprehensive assessment of cognitive, motor, social and behavioural development and lung function. ETHICS AND DISSEMINATION: The study has approval from the Royal Children's Hospital Human Research Ethics Committee, Melbourne, Australia. The findings will be disseminated via peer-reviewed journal publications, conference presentations, digital and print media and through parent support/network groups.
