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
Phospholipids are key regulators of immune metabolism, yet their specific influence on macrophage function remains incompletely defined. We investigated how phosphatidylethanolamine (PE) species with distinct acyl chains (PE18:0/22:6 and PE18:0/20:4) modulate RAW264.7 macrophages under resting and LPS-stimulated conditions using LC-MS/MS-based proteomics and metabolomics, followed by qPCR validation. LPS elicited a robust M1-like phenotype with strong upregulation of Ptgs2, Nos2, Nfkb1, and Nfkb2. PE supplementation alone did not induce a classical pro-inflammatory profile but significantly remodeled protein expression, enhancing antioxidant defenses, including catalase, Hmox1 and Prdx1. In the context of LPS activation, PE selectively attenuated inflammatory signaling by downregulating Nfkb1, Nfkb2, and Ptgs2 while further enhancing proteins linked to oxidative stress response (Prdx1 and Hmox1) and lipid metabolism (CD36 and Abcc1). qPCR corroborated these effects: both PE species reduced LPS-induced
