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

The stimulator of interferon genes (STING) is a critical mediator of innate immunity against cytosolic DNA pathogens, requiring precise regulation to balance antiviral defense and immune tolerance. While lipid metabolism influences immune signaling, the role of stearoyl-CoA desaturase 1 (SCD1), a key enzyme converting saturated fatty acids (SFAs) to monounsaturated fatty acids (MUFAs), in STING activation remains unexplored. Here, we identify SCD1 as a metabolic checkpoint that licenses STING activation through biophysical membrane remodeling. Mechanistically, SCD1-generated MUFAs incorporate into endoplasmic reticulum (ER) phospholipids, enhancing membrane curvature and fluidity. This biophysical remodeling facilitates cyclic guanosine monophosphate (GMP)-adenosine monophosphate (AMP) (cGAMP) binding to STING and promotes its dimerization, enabling downstream TBK1-IRF3 signaling and type I interferons (IFNs) production. Consequently,
