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
Regulatory T cells (Tregs) maintain immune homeostasis in vivo. Similar to conventional T cells (Tconvs), Tregs are divided into naïve and memory cells. Tregs have unique metabolic properties, including enhanced oxidative phosphorylation. The lipidomic profiles of human Tregs have been studied previously; however, those of naïve and memory Tregs have not yet been consistently compared. Thus, in the present study, we used a combined transcriptomic and lipidomic analysis to assess the metabolic features of human naïve and memory Tregs upon activation. Using transcriptomic analysis, we identified distinct gene expression profiles in naïve and memory Tregs compared with those in Tconvs. Upon TCR stimulation, memory Tregs showed a lipidomic profile distinct from that of memory Tconvs, whereas the lipidomic profiles of naïve Tregs were similar to those of naïve Tconvs. Furthermore, upon TCR stimulation, memory Tregs expressed triglycerides (TGs) that were more enriched in monounsaturated fatty acids and polyunsaturated fatty acids (PUFAs) than those of memory Tconvs. However, memory Tconvs also had higher PUFA-TG levels than naïve Tconvs and Tregs after TCR stimulation, although their levels remained lower than those in memory Tregs. These findings suggest PUFA-TGs could be a marker of memory Tregs. In turn, higher frequency of memory cells within the Treg population may also contribute to the observed enrichment of PUFA-TGs in Tregs upon TCR activation. Our study demonstrated unique transcriptomic and lipidomic profiles and enhanced lipogenesis in memory Tregs upon TCR stimulation.
