Design, implementation and outcomes of a national oxygen distribution network in Lesotho.
Observational study in BMJ global health, 2025. 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
backgroundDespite its essential and life-saving role in the treatment of many medical conditions, access to medical oxygen remains limited in many countries. In 2021, Partners In Health established an oxygen distribution network in Lesotho to increase medical oxygen access.
methodsWe conducted an observational study reporting on the design, implementation, and outcomes of a national oxygen distribution network in Lesotho from November 2022 through January 2024. Oxygen delivery data were abstracted from tracking logs and analysed in Stata. Continuous and ordinal variables were summarised by medians and ranges. Categorical variables were described using frequencies and proportions.
resultsOver the 15 month study period, the network expanded from one oxygen production hub serving five recipients to four hubs and 21 recipients located across nine of Lesotho's 10 districts. The network delivered 1565 filled cylinders containing 9619.23 m
conclusionThis study demonstrates the feasibility of an oxygen distribution network in Lesotho, providing proof-of-concept for an intervention to improve oxygen access in low- and middle-income countries. By employing real-time monitoring and redundant sourcing, the network provided a reliable oxygen supply responsive to variations in demand and periods of oxygen plant downtime. This study also provides insights into facility-level oxygen consumption, which may help policymakers improve quantification and prediction of oxygen demand. Future efforts should focus on enhancing data collection, characterising oxygen usage and strengthening infrastructure to promote sustainable oxygen security.
