Health infrastructure under pressure: spatial-temporal analysis of King Saud Medical City expansion.
Article in Frontiers in health services, 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
King Saud Medical City (KSMC), Riyadh's largest public medical city, has undergone a profound spatial and institutional transformation between 2000 and 2025. Using multi-temporal remote sensing and geographic information system analysis, this study provides quantitative evidence of medical city densification in Saudi Arabia. The built-up footprint expanded by more than 19 hectares, and the Normalized Difference Built-up Index increased by +0.36, reflecting a shift from a low-rise, dispersed campus to a vertically integrated medical complex. This physical transformation coincided with major institutional growth: total bed capacity increased from approximately 450 to over 1,500, including 200 intensive care beds; the emergency department expanded to 102 beds, becoming one of the largest in the Kingdom; and annual surgical volume exceeded 20,000 major procedures. These changes occurred alongside rapid population growth in Riyadh and national health system reforms such as the Medical Cities Law, the Health Cluster Model, and Vision 2030. The findings demonstrate how spatial densification enabled operational expansion and accelerated the adoption of advanced medical infrastructure. The study offers a scalable spatial framework for guiding the future development of large medical facilities in rapidly urbanizing settings.
