The key role of the Southern Annular Mode during the sea-ice maximum for Antarctic sea ice and its recent loss.

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
Antarctic sea ice exhibits considerable interannual variability and has experienced unprecedented decline over the past decade. Here we provide observational insights into the role of the Southern Annular Mode in driving such variations in Antarctic sea-ice area. The influence of the Southern Annular Mode on Antarctic sea-ice area exhibits more pronounced seasonality than indicated in previous work. Positive anomalies in the Southern Annular Mode lead to decreases in sea-ice area during the seasonal sea-ice maximum, but vice versa during the sea-ice minimum. Variations in Southern Annular Mode during the sea-ice maximum also have an outsized influence on annual-mean changes in sea-ice area, since the seasonally-varying persistence and shortwave effects of sea-ice anomalies peak during the following months. It is argued that a notable fraction of the dramatic losses in annual-mean sea-ice area over the past decade can be traced to variations in the Southern Annular Mode during the sea-ice maximum.
