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 observation of phase separation in intact plasma membranes isolated from live cells is a breakthrough for research into eukaryotic membrane lateral heterogeneity, specifically in the context of membrane rafts. These observations are made in giant plasma membrane vesicles (GPMVs), which can be isolated by chemical vesiculants from a variety of cell types and microscopically observed using basic reagents and equipment available in any cell biology laboratory. Microscopic phase separation is detectable by fluorescent labeling, followed by cooling of the membranes below their miscibility phase transition temperature. This protocol describes the methods to prepare and isolate the vesicles, equipment to observe them under temperature-controlled conditions and three examples of fluorescence analysis: (i) fluorescence spectroscopy with an environment-sensitive dye (laurdan); (ii) two-photon microscopy of the same dye; and (iii) quantitative confocal microscopy to determine component partitioning between raft and nonraft phases. GPMV preparation and isolation, including fluorescent labeling and observation, can be accomplished within 4 h.
