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

Lipid-protein interactions are ubiquitous in biology, where they are fundamental to membrane structure, cell signaling, immunology, and metabolism. Despite the availability of thousands of experimentally determined lipid-protein structures, the molecular basis for lipid recognition and specificity across the lipid-protein interactome remains incompletely understood. Here, we report a systematic analysis of 113,782 annular and nonannular lipid-protein complexes spanning the eight lipid classes. Pairwise atomic interactions are linked to lipid and protein physicochemical properties and binding geometries. Hydrophobic contacts, hydrogen bonds, and salt bridges contributed to over 99% of lipid-protein interactions. Lipid class-, protein sublocalization-, protein function-, and protein fold-dependent trends were identified. Protein pockets were finely tuned for lipid size, shape, and polarity: fatty acyls associated with narrow, moderately hydrophobic pockets; saccharolipids and glycerophospholipids bound to larger, polar cavities; and sterols and prenols preferentially occupied compact hydrophobic sites. Global analysis across different protein families identified similarities in interaction profiles, while also highlighting protein-specific recognition adapted to biochemical function. Lipid-protein interaction maps were projected onto lipid structures to uncover conserved and divergent hotspots and coldspots across lipid classes. The heatmaps imply that recognition and specificity are mediated by tailored anchoring of polar head groups and varying interaction with hydrophobic tails. Together, the data establish nature's principles governing lipid binding, lipid selectivity, and complex stability, and collectively provide a molecular atlas of the lipid-protein interactome. The work enables the elucidation of lipid biology at scale and establishes guiding principles for the rational design of chemical probes and therapeutics targeting lipid biology.
