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 physiological role of lipid asymmetry in intracellular membranes remains poorly understood. Here, we show that sphingomyelin (SM), typically confined to the lumen of the trans-Golgi network (TGN), is exposed on its cytoplasmic surface by the action of the Golgi-associated protein, Golgi-associated gamma-adaptin ear-containing adenosine 5'-diphosphate-ribosylation factor-binding protein 1 (GGA1). This exposure is driven by the GGA1 GAT domain, which induces lipid scrambling in a manner dependent on membrane curvature and cholesterol. SM exposure coincides with the exit of mannose 6-phosphate receptors from the TGN, a process essential for lysosomal enzyme trafficking. Furthermore, SM is transferred to autophagic membranes, where it facilitates autophagosome-lysosome fusion. These findings reveal a previously unrecognized role for lipid remodeling in membrane trafficking and autophagy.
