Benthic fauna on the edge between different seas-signs of climate change in the Sound (Öresund)?

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 major goal of this study was to identify long term (1998-2022) changes within the macrobenthic communities in the Sound (Öresund), with special emphasis on climate change. Bottom trawling in this area has been banned since 1932. This was compared to changes of the same species at the surrounding Swedish west coast in the north (the Kattegat and the Skagerrak) and the Baltic Sea in the south. Results are also related far back in time in the Sound as the benthic fauna has been unusually well-studied since the 1800s. It is of special interest to study the faunal response to the rise in bottom water temperature which has been recorded in later years. The Sound between Denmark and Sweden is situated between the Baltic Sea, one of the largest brackish waters, and the Kattegat, an extension of the Atlantic. This location provides special conditions for a benthic fauna with a northern touch. Brackish water species typical of the Baltic occur here, but also marine cold-water species typical of the Arctic. Many species therefore live on their edge of distribution in the Sound. The development in abundance 1998-2022 in the Sound with its trawl-ban was similar to heavily trawled areas along the Swedish west coast. Species with a northern distribution were found to decrease parallel with an increase in species with a southern distribution. The sharper reduction in abundance in the Sound compared to surrounding seas may be due to the fact that many species here live at the extreme edge of their range. Indications of disturbed reproduction and submergence in some northern species were also recorded. The most likely explanation of these changes is the increase in temperature which affects many processes that may act in synergy. The transition from a
