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

The issue of facility location is of significant importance in numerous systems, where the efficient utilisation of resources is of great importance. Gravity models, which are inspired by Newtonian physics, are commonly employed to address these problems and have a long tradition of being used in healthcare. The objective of this paper is to enhance the comprehension of patients' decision-making processes in emergency healthcare by introducing an extension to existing gravity models, which includes two novel factors influencing emergency department choice: hospital sizes and patients' severity. The newly formulated gravity rule, which integrates these factors, demonstrated an extremely high accuracy against real-world data in terms of overall hospital location and flows between cities and hospitals, respectively 98.77% and 98.02%.
