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 wildland-urban interface (WUI) fires have adverse effects on both physical and mental health. However, early biosignals changes related to fires are not well understood. Digital wearables can capture real-time changes in physiological stress and activity patterns, providing insight into the mechanisms of health effects of WUI fires and identifying vulnerable populations during and after WUI fires. This study aimed to assess the immediate and sustained changes in physical activity patterns and physiological stress markers during and after the 2025 Los Angeles wildfires. We conducted a longitudinal study of 15 older adults (mean age 73.2 years) during the 2025 Eaton Fire in Los Angeles, using the digital Oura Ring (Gen 3) continuously. Data were collected at baseline (Dec 9th, 2024 to Jan 6th, 2025), during the fire (Jan 7th, 2025 to Jan 12th, 2025), and after the fire (Jan 13th, 2025 to Jan 27th, 2025). Daily activity patterns (physical activity and sleep duration) and physiological stress (sleep heart rate, heart rate variability, sleep fragmentation, and breath rate) were collected, and linear mixed-effects models were used to investigate how these biosignals changed and how evacuation alerts impacted these changes. During the fire, six out of fifteen participants received evacuation alerts. We observed a 41-minute increase in sedentary time (
