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

Hypoxia in solid tumors is associated with poor outcomes because of metabolic adaptations that support tumor cell survival and alter immune cell function. However, the metabolic and phenotypic adaptations of macrophages (MФs) to chronic hypoxia (CH) remain unclear. This study identifies impaired activity of the oxygen-dependent enzyme stearoyl-CoA desaturase 1 (SCD1) as a driver of altered fatty acid (FA) metabolism in MФs under CH. SCD1 deletion enhanced pro-inflammatory gene expression while suppressing the production of the chemokine CCL22. We propose that attenuated SCD1 activity and an altered saturated fatty acids (SFA)/monounsaturated fatty acids (MUFA) ratio impair the function of the transcription factor HNF4α, thereby affecting the expression of inflammatory genes such as CCL22. Reduced CCL22 levels, in turn, impaired γδ T cell recruitment. Accordingly, CCL22 expression in non-small cell lung cancer patients correlated positively with γδ T cell frequency and patient survival. These findings highlight the immunometabolic role of SCD1 in the hypoxic tumor microenvironment.
