The epidemic and socioeconomic factors shock: a long-term dynamic analysis of equity in infectious disease healthcare in China.
Article in International journal for equity in 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
objectivesTo analyze the changes in equity of health resources and service utilization (HRSU) for infectious diseases and to assess the impact of COVID-19 and its associated socioeconomic changes on this equity.
methodsThis study utilized 14-year provincial panel data from 31 provinces in mainland China. Data were sourced from the China Health Statistics Yearbook (2011–2024). Equity in infectious disease HRSU was assessed using four key indicators. Specifically, health resource indicators included the number of CDC physicians and infectious disease beds, while service utilization indicators included the infectious disease outpatient rate and inpatient rate. A GDP-weighted Theil index was applied to analyze equity before and after the COVID-19 pandemic, and an Interrupted Time Series Analysis (ITSA) was conducted to quantify the pandemic’s impact on equity.
resultsPost-COVID-19, the Theil index decreased for CDC physicians, infectious disease beds, utilization of outpatient service (UOS) and utilization of inpatient service (UIS). ITSA showed that after the pandemic, the pandemic had a statistically significant impact on the Theil index of infectious disease beds and UIS, with the difference between the pre-pandemic and post-pandemic slopes of -0.0132 and - 0.0077 (p < 0.001). Conversely, the Theil index of UOS decreased immediately after the pandemic (β2= -0.0106, p < 0.001), but there was no sustained effect.
conclusionEpidemic shocks have catalyzed policy responses, driving sustained gains in equity for infectious disease beds and inpatient service access, but only transient improvements in equity of UOS. The epidemic’s socio-economic impacts and inherent regional-economic disparities exert long-term effects on healthcare equity. A Health Priority Development Strategy could contribute to lowering infectious disease incidence and promoting sustained equity in health service utilization. CLINICAL TRIAL NUMBER: Not applicable.
