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

objectivesThe aims of the study were to determine the prevalence of suspected developmental delay in children living in poor areas of rural China and to investigate factors influencing child developmental delay.

designA community-based, cross-sectional survey was conducted.Eighty-three villages in Shanxi and Guizhou Provinces, China.

participantsA total of 2514 children aged 6-35 months and their primary caregivers. OUTCOME MEASURES: Suspected child developmental delay was evaluated using the Ages & Stages Questionnaires-Chinese version. Caregivers' education and age, wealth index, child feeding index, parent-child interaction, number of books and Zung Self-Rating Depression Scale were reported by the primary caregivers. Haemoglobin levels were measured using a calibrated, automated analyser. Birth weight was obtained from medical records.

resultsOverall, 35.7% of the surveyed children aged 6-35 months demonstrated suspected developmental delay. The prevalence of suspected developmental delay was inversely associated with age, with the prevalence among young children aged 6-11 months being almost double that of children aged 30-35 months (48.0% and 22.8%, respectively). Using a structural equation model, it was demonstrated that caregiver's care and stimulus factors and child's haemoglobin level were directly correlated, while caregiver's sociodemographic factors were indirectly associated with suspected developmental delay.

conclusionsThe prevalence of suspected developmental delay is high in poor rural areas of China, and appropriate interventions to improve child development are needed.
