Decreasing aerosols increase the European summer diurnal temperature range.

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.
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 diurnal temperature range (DTR), the difference between daily maximum and minimum temperature, is important for the impact of extreme temperatures, but despite physical links to aerosol forcing previous studies have struggled to attribute observed DTR changes to aerosols. Using causal inference, we can clearly identify aerosols as a driver of European DTR change since 1940. Following a decrease from the 1940s, since the 1980s the European DTR has increased by about 0.5K due to a reduction in European aerosol emissions leading to cooler nights relative to days. Agreement between causal effects estimated from observations with those estimated for two CMIP6 models evaluates the models' microphysical and radiative parameterizations. From causal effects, we also derive effective radiative forcing estimates of aerosols on surface shortwave during European summer, which amount to [-1.7; -1.5] Wm
