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

Brown adipose tissue (BAT) is crucial for non-shivering thermogenesis, a key adaptation for humans in Arctic environments. The discovery of BAT presence in human adults has ignited curiosity due to its potential role in combating obesity, type II diabetes and cardiovascular diseases. Following PRISMA guidelines and preregistration (PROSPERO CRD42023444511) this systematic review aims to describe the evidence of BAT activity among adults living in the Arctic with habitual cold exposure. Systematic searches were conducted in PubMed, Embase, and Scopus as of November 2024. In addition, trial registration searches, manual screening of reference lists, and requests to experts were performed. No restrictions were made regarding study selection. Each study was assessed using the NIH Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Of 429 studies screened, 21 full texts were included for eligibility assessment, and eight studies qualified for inclusion. Due to the heterogeneity of the included studies, a meta-analysis was not pursued. Results indicate high BAT activity in Arctic populations, as supported by increased supraclavicular skin temperatures after cold exposure, thyroid hormone dynamics, and genetic markers linked to BAT. Findings highlight BAT's role in cold adaptation among adults residing in Arctic regions, though methodological limitations remain, necessitating further research.
