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

Humans undertake physical activity daily, yet we know little about how climate change might affect this fundamental aspect of life. Using 24 billion person-minute observations from a sample of Fitbit users in the United States, this paper estimates behavior and performance responses to extreme temperatures. I find significant reductions in activity on hot and cold days, though intraday and interday substitution mitigate this effect. Regions with hotter climates are less sensitive to extreme heat, evincing adaptation. Physical activity projections incorporating this heterogeneity and allowing places to adapt to their future climate imply large welfare gains, unlike projections that ignore adaptation.
