Secular Trends of Ascariasis Infestation and Nutritional Status in Chinese Children From 2000 to 2014: Evidence From 4 Successive National Surveys.
Article in Open forum infectious diseases, 2019. 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
backgroundThis study aimed to assess secular trends and epidemiological status of ascariasis infestations and to explore its effects on the nutritional transition among Chinese children from 2000 to 2014.
methodsData were collected from 69 435 Chinese children aged 7-year-olds and 9-year-olds in 4 successive cross-sectional surveys of Chinese National Survey on Students' Constitution and Health. Ascariasis infestation was defined by using the Kato-Katz method. Nutritional status was classified into stunting, thinness, overweight, and obesity by WHO definition.
resultsFrom 2000 to 2014, the ascariasis infestation rates decreased from 9.1% to 1.7%, the stunting and thinness prevalence decreased from 4.3% and 13.8% to 0.7% and 7.1%, while the overweight and obesity prevalence increased from 3.6% and 2.1% to 9.8% and 9.1%, respectively. Compared to children in the ascariasis noninfestation group, those infected with ascariasis had a worse nutritional status. Yet, the disparity in nutritional status between 2 groups disappeared over time. Provinces with a higher gross domestic product per capita simultaneously had lower ascariasis infestation rates, lower stunting and thinness prevalence, and higher overweight and obesity prevalence.
conclusionsThe retardation effects caused by ascariasis infestation on nutritional status in Chinese children seemed to be offset by the rapid economic development and nutritional transition over time; nevertheless, multiple prevention and control measures are still needed and should be continuously strengthened.
