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
Endoplasmic reticulum (ER)-plasma membrane (PM) tethering is crucial for the non-vesicular lipid transport between the ER membrane and the PM. However, the PM-associated ER can impede the PM binding of cytoskeletons and other organelles. It is poorly understood how the competition between the ER and cytoskeletons/organelles on the PM is resolved. Here, we show that, upon septin collar assembly, ER-PM tethering proteins are excluded from the yeast bud sites, and the PM-associated ER is locally detached from the PM. Our results suggest that PM flows by polarized exocytosis extrude PM proteins, including ER-PM tethering proteins, from the bud sites. When the reorganization of the ER-PM tethering was inhibited by exocytosis repression, septin localization was restricted to the PM sites poor in ER-PM tethering proteins. This study proposes machinery reconciling ER-septin competition on the PM, providing mechanistic insights into the spatial organization of PM-associated organelles and cytoskeletons.
