PI3P regulates multiple stages of membrane fusion.
Article in Molecular biology of the cell, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
The conserved catalysts of intracellular membrane fusion are Rab-family GTPases, effector complexes that bind Rabs for membrane tethering, SNARE proteins of the R, Qa, Qb, and Qc families, and SNARE chaperones of the SM, Sec17/SNAP, and Sec18/NSF families. Yeast vacuole fusion is regulated by phosphatidylinositol-3-phosphate (PI3P). PI3P binds directly to the vacuolar Qc-SNARE and to HOPS, the vacuolar tethering/SM complex. We now report several distinct functions of PI3P in fusion. PI3P binds the N-terminal PX domain of the Qc-SNARE to enhance its engagement for fusion. Even when Qc has been preassembled with the Qa- and Qb-SNAREs, PI3P still promotes
