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 rapid expansion of sensor technologies and location-enabled mobile applications has greatly advanced the study of human mobility. Recently emerged sources like mobile app data offer outputs similar to traditional datasets-trip chains, flows, and indicators-but the methods and decisions used to process such data often vary across location, time, and policy context and remain poorly documented and insufficiently transparent. This variability necessitates tailored data processing and validation approaches, which remain underexplored in existing literature. This study aims to provide a reproducible and replicable framework for processing location-points data, using a case study of anonymised mobility records collected in November 2021 across England. We describe a modular workflow and multi-stage validation techniques that enhance the reproducibility of stay-point detection and activity labelling. Furthermore, we demonstrate how the proposed framework can generate reliable mobility indicators and origin-destination flow matrices for broader research applications. The resulting datasets-including sampled anonymised trajectories and full origin-destination flow matrices-are publicly available for research purposes, with updates to code and methodology hosted on GitHub and Zenodo.
