Assessment of radiological capacity and disparities in TB diagnosis: a comparative study of Mozambique, South Africa and Spain.
Article in BMJ public health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Tuberculosis (TB) remains a significant global health challenge, particularly in children, where diagnosis is challenging. Radiological resources such as chest X-rays and CT scans play a crucial role in early screening and diagnosis, especially in the absence of microbiological confirmation of disease. However, radiological capacity and access vary widely across regions and countries. Methods: This study retrospectively audited licensed X-ray and CT units in Mozambique, South Africa and Spain in 2022. Population data were used to calculate units per million people. The study used choropleth maps to visualise regional disparities and to explore potential interactions between radiological capacity, population density and TB notifications. Results: Mozambique had the lowest radiological capacity, with 3.6 X-ray units and 0.4 CT units per million people, compared with South Africa's 34.2 X-ray units, 5.8 CT units and Spain's 811.5 X-ray units and 19.3 CT units. The private sector exhibited higher capacity than the public sector in all countries. Regional disparities were evident, particularly in Mozambique, highlighting urban-rural discrepancies and in-country inequalities. Conclusion: This study underscores significant disparities in radiological capacity between low-income, middle-income and high-income countries, with economic factors playing a pivotal role. Addressing these disparities is crucial for improving TB and other disease diagnostic capabilities, particularly in resource-limited settings. Potential solutions include establishing dedicated national radio-diagnostic departments, developing national guidelines and integrating portable AI-powered X-ray or point-of-care ultrasonography technology. These findings provide valuable insights for policymakers and stakeholders to advocate for improved radiological resources and equitable healthcare access.
