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

Understanding food security level on a large scale is crucial for grasping global food security and issuing timely warnings about regional food systems risks. Current regional spatiotemporal distribution and multidimensional comparisons of global food security are insufficient. Therefore, this paper proposed a weighting technique combing the subjective AHP method with the objective CRITIC method, and developed a new composite index to measure food security multidimensionally. Using the food security composite index (FSCI), this study explored the spatiotemporal evolution of food security in different dimensions at both global and regional levels, based on panel data from 2001 to 2020. The variation of FSCI remained stable in the quantity dimension across all regions, with significant improvements in economic security observed in Europe and Latin America and Caribbean, and Asia showed an upward trend in resource dimension. Compared to the global average, Europe had a pronounced advantage, whereas Sub-Saharan Africa had a significant disadvantage.
