Association between dietary diversity in complementary feeding and growth and nutritional status among children aged 0-36 months in China: a cross-sectional study.

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
Objective: To assess complementary feeding practices among Chinese parents and to investigate the associations between dietary diversity in complementary feeding and growth outcomes in children aged 0-36 months. Methods: This national cross-sectional study included 26,266 children aged 0-36 months from 33 provinces in China. Participants were recruited through a convenience sampling strategy. Self-reported questionnaires were designed and posted on the website of the China Maternal and Child Health Association, which collected the information of assessing complementary feeding practices and knowledge. Anthropometric indicators (length/height, weight, and weight-for-length/height) were evaluated using World Health Organization growth standards. Dietary diversity was defined based on the daily consumption of multiple complementary food groups. Correlation analyses and multivariable regression models were conducted to evaluate associations between dietary diversity, specific food groups, and growth outcomes. Results: A high proportion of children were classified above the 90th percentile for weight across regions (range: 39.39-51.83%). Dietary diversity was positively associated with linear growth in all age groups, with the strongest association observed among children aged 19-36 months ( Conclusion: Chinese children aged 0-36 months may be at risk of high body weight status. Greater dietary diversity in complementary feeding may support optimal linear growth while helping to mitigate excessive weight gain. Given the observed gap between parental knowledge and feeding practices, targeted nutrition education and guidance on responsive feeding are urgently needed from a public health perspective.
