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

Background: Automated brain tumor segmentation on multi-parametric magnetic resonance imaging (mpMRI) is crucial in assessing patient outcomes and remains a challenge across Sub-Saharan Africa (SSA). Since 2012, the Brain Tumor Segmentation (BraTS) Challenge has evaluated state-of-the-art artificial intelligence (AI) methods to detect, characterize, and classify tumors. However, it is unclear if these methods can generalize, and hence be widely implemented, in SSA populations. To address this, the BraTS-Africa challenge was conducted in 2023 and 2024 to evaluate population-specific AI models for automated segmentation of brain tumors on mpMRI from the region. Methods: Preoperative T1-weighted, T1-contrast enhanced, T2-weighted, and T2-FLAIR brain MRI scans of 115 patients diagnosed with adult diffuse glioma were curated, annotated, and utilized for the Challenge. Participants were invited to develop and validate their methods. The participating teams were evaluated using weighted Dice Score Coefficient (DSC) and 95% Hausdorff Distance (HD95). Results: In the 2023 challenge a total of 9 teams with participants from 12 countries met the submission criteria and were ranked. The 2024 challenge featured 6 teams from 7 countries. Compared to 2023, the six top ranked methods from 2024 had higher DSC (9.4%) and lower HD95 (57.21%). Conclusions: Together, the 2023 and 2024 challenges provided a unique opportunity to include brain mpMRI glioma cases from SSA in global efforts to develop and evaluate AI methods for the detection of glioma boundaries and their quantification, where the potential of AI solutions to transform healthcare into resource-limited settings is more likely.
