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

In the past two decades, global cities have experienced a decline in urban population density, marked by urban land expansion outpacing population growth. The impact of this trend on urban population exposure to surface urban heat island (SUHI) has not been fully examined by considering the intra-city spatial variations in both population distribution and surface temperature. In this study, we examine the temporal trends of population-weighted SUHI extremes (as a proxy for spatial heat exposure) in the 1,000 largest global cities using high-resolution data from 2003 to 2020. Our findings reveal that cities with declining population densities experience a slower increase in population-weighted SUHI extremes compared to the rise in the area-average values, by approximately 0.5 ± 0.04 K per decade for every 1,000 persons/km
