Estimates for sensory impairments requiring rehabilitation in China and globally: a comparative analysis of trends from 1990 to 2021 and future projections based on the GBD-WHO rehabilitation database 2021.
Article in Journal of global 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: Sensory impairments, especially hearing and vision loss, are an increasing global public health concern. We examined the burden and trends of sensory impairment rehabilitation needs in China from 1990 to 2021 by age and sex, compared them with global data, and projected trends for the next 15 years. Methods: Using data from the World Health Organization rehabilitation need estimator, we analysed prevalence, years lived with disability (YLDs), and age-standardised rates (ASRs) at national and global levels. We calculated the average annual percent change (AAPC) using Joinpoint regression to identify significant trend shifts. We projected future trends using the Bayesian age-period-cohort model and decomposition analysis to assess the contributions of key drivers. Results: From 1990 to 2021, China experienced a more pronounced increase in the number of prevalent cases requiring sensory impairment rehabilitation (140.60%) than the global average (98.09%). The age-standardised prevalence rate (ASPR) increased significantly in China (AAPC = 0.2805), largely driven by hearing loss (AAPC = 0.4204), whereas the global ASPR increased only modestly (AAPC = 0.0797). Similarly, the age-standardised years lived with disability rate (ASYR) increased in China (AAPC = 0.1005) but declined globally (AAPC = -0.0955). Sensory impairments requiring rehabilitation were most prevalent among older adults (aged 55-79 years). Males were more affected at younger ages, whereas females were more affected at older ages. Decomposition analysis identified population ageing as the dominant driver in China. Projections indicate a slight decline in China's ASPR over the next 15 years, accompanied by a decline in ASYR. Globally, both metrics are expected to decline slightly. Conclusions: Population ageing is the main driver of China's rapidly growing need for sensory impairment rehabilitation, outpacing global trends. Urgent public health strategies are needed to strengthen rehabilitation systems and target older adults.
