An Arctic Ocean Thermohaline Dataset.
Article in Scientific data, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Using in situ observational data is an important way to study the Arctic environment. However, due to the high-latitude seasonal variation, in situ observations in this region are relatively sparse. To maximize the use of in situ observations, we assemble an Arctic Ocean thermohaline dataset (AOTD) including 414221 available temperature and salinity profiles for the period 1983-2023, with observations from the Chinese Arctic Research Expedition and public data from other databases and observations plans such as the International Polar Year. Also, a unified quality control method is discussed, and strict quality control is applied to these profiles. A gridded dataset of climatological monthly mean temperature, salinity, and Ocean Heat Content derived from an objective analysis of profiles is also presented. The climatology has a horizontal resolution of 0.25° × 0.25°, with 57 vertical layers spanning the 0-1500 m depth range, can help us better understand the Arctic Ocean. AOTD climatology offers importance for the research on thermodynamic processes, spatial and temporal variability of water masses, and oceanic structures in the Arctic Ocean.
