Temporal trend and influencing factors of high-risk pregnancy in China: a nationwide longitudinal analysis.
Article in Frontiers in public health, 2026. 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
Background: High-risk pregnancy was a major challenge to sustainably reduce maternal mortality rate to achieve the Sustainable Development Goals in China. This study aimed to analyze the temporal trend of high-risk pregnancy rate in China and to explore the influence of socioeconomic factors. Methods: Panel data of 31 provinces in China from 2002 to 2016 were extracted from the China Statistical Yearbooks and Health Statistical Yearbooks. We firstly adapted JoinPoint regression model to describe the temporal trend of high-risk pregnancy rate. Then, an auto-regressive integrated moving average model was built to predict high-risk pregnancy rate from 2017 to 2030. Finally, a linear mixed model was employed to evaluate the impact of socioeconomic factors on high-risk pregnancy rate at the provincial level. Results: The high-risk pregnancy rate increased substantially with an average annual percent change of 6.06% (95% CI: 5.70, 6.51%) from 1996 to 2016 in China. Except Tibet, the high-risk pregnancy rate of other 30 provinces all presented an upward trend with an average annual percent change ranging from 1.86% (95% CI: 1.47, 2.35%) to 11.15% (95% CI: 9.22, 13.10%). The predicted high-risk pregnancy rate would up to 38.76% (95% CI: 31.66, 45.85%) in 2030 in China. The number of hospital beds per 1,000 population was negatively associated with high-risk pregnancy rate ( Conclusion: The high-risk pregnancy ratio in China has been increasing and sustains an upward trend, posing great challenge to maternal health improvement in China. Healthcare resources and other socioeconomic factors have significant effect on high-risk pregnant rate, such findings can provide evidence-based implications for long-term policy-making in healthcare resource allocation, urban development and gender equality. Constant efforts by all society should be made to enhance maternal health to achieve the goals of the Sustainable Development Goals and Healthy China 2030.
