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

We use a unique combination of (paleo-)reanalysis (ModE-RA, ERA5) and model simulations (ModE-Sim) to examine extreme summer heat events in Central Europe over the past 600 years (1421-2008) and compare their occurrences to CMIP6 future climate projections. Using a common, fixed climatology, 2003 was identified as the hottest summer of the past 600 years. However, using a moving climatology approach, we identify 1540 (April–September, +2.2 [Formula: see text]C) and 1590 (June–August, +2.8 [Formula: see text]C) as the most extreme summer anomalies. The two summers differ in their temporal development, their impacts, and partly their atmospheric circulation patterns. We then analyze similarly anomalous summers in two sets of CMIP6 projections and the ModE-Sim ensemble and connect their occurrence to sea surface temperature anomalies over the North Atlantic. ModE-Sim, which comprises 11,760 model years, produces 0.14% (April-September) and 0.24% (June-August) Central European summers with temperature anomalies from a moving climatology surpassing 1540 and 1590. In CMIP6 projections such anomalies are more frequent, but none reaches the magnitude of the largest June-August anomaly in ModE-Sim which exceeds 4 [Formula: see text] [Formula: see text]C. A similarly extreme anomaly in a future climate could dramatically affect ecosystems and societies. Overall, the combination of reanalysis and model simulations provides a unique and comprehensive framework for understanding the drivers of past and future summer heat extremes.
