Power supply and ultrasound functionality in Malawi: findings from the 2019 harmonised health facility assessment.
Article in npj health systems, 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
Ultrasound sonography is a critical diagnostic tool, yet access remains limited in Malawi. This study assessed the relationship between electricity supply and ultrasound availability and functionality using data from 596 health facilities in the 2019 Harmonised Health Facility Assessment. Only 9.9% of facilities had ultrasound equipment available, with 93% of that equipment functional. Facilities powered by non-grid sources were 86% less likely to be functional (PR: 0.14; 95% CI: 0.02-0.49) compared to those with a stable grid supply. Ultrasound functionality was particularly low in primary-level facilities and those owned by the government. Spatial analysis revealed that most facilities without ultrasound were located in energy-constrained areas. While electricity access is necessary, it is insufficient on its own. Results support the need for stronger alignment between the health and energy sectors, as well as the potential for targeted deployment of handheld ultrasound in low-resource, off-grid settings.
