1 · What the graph read from it

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.

2 · The registry

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

Limited access to neuroimaging remains a major constraint on neurological care in many low-resource areas. We conducted a descriptive landscape analysis of neuroimaging access in Chad using hospital-reported data, publicly available healthcare and infrastructure data, and contextual information from clinicians and radiology personnel at major hospitals in N'Djamena. This analysis characterizes key constraints on neuroimaging access in Chad and highlights practical considerations for expanding imaging capacity in resource-limited settings. Chad has only one magnetic resonance imaging scanner for a population of approximately twenty-one million. The country's major hospitals and imaging workforce are concentrated in the capital, and the sole MRI system is an older 0.35 T scanner located at a private hospital. Access is further limited by scan cost, geographic centralization, unreliable electricity, limited technical support, and shortages of trained imaging personnel. Hospital data indicate a substantial burden of neurological conditions, particularly stroke and neurological infections, for which imaging can be important for diagnosis and management. We place these findings in the context of emerging lower-cost, compact, and mobile magnetic resonance imaging technologies. Such systems may reduce some infrastructure and siting requirements, but limitations related to image quality, maintenance, workforce capacity, and long-term sustainability remain important considerations.
