Assessing three-decade HIV testing transformation: TOPSIS-radar evaluation of tiered health system performance in rural-urban Southwestern China.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundChina's expanded HIV testing program (since 2015) necessitates longitudinal evaluation of healthcare institution (HCI) performance, which provides critical evidence to enhance the precision and effectiveness of focused testing interventions, to optimize service delivery.
methodsWe analyzed HIV surveillance data from 202 HCIs in Nanning, China (1989-2020), characterizing: 1) HCI infrastructure distribution, 2) newly reported HIV/AIDS cases and testing volumes, and 3) test positivity rates. Spatiotemporal trends were geo-visualized (ArcGIS 10.7). TOPSIS synthesized case reports and test positivity rates (2010-2020) into composite indices, with radar mapping identifying regional disparities.
resultsReporting shifted from CDC-dominated systems (99.9%, 1989-2004) to hospital-led models (75.6%, 2015-2020). While annual testing volume and case reports increased significantly, test positivity rates declined. Distinct hospital-level stratification emerged: County/township HCIs served primarily local residents (96.2%) and older patients (≥ 50 years; 65.7%). Municipal/provincial HCIs reported higher non-local residents (48.6%) and younger patients (15-49 years; 53.4%). Geospatial diffusion showed progression from urban to rural areas. Regions with integrated AIDS treatment centers and robust primary care networks demonstrated enhanced case-finding performance.
conclusionsTiered hospitals and primary care centers may provide complementary case-finding functions. Geographically stratified interventions, which leveraged primary networks for localized epidemics and referral hospitals for mobile populations, represent evidence-based strategies for regions with suboptimal performance.
