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 bilayer membranes found in nature are heterogeneous mixtures of lipids and proteins. Model systems, such as supported lipid bilayers (SLBs), are often employed to simplify experimental systems while mimicking the properties of natural lipid bilayers. Here, we demonstrate a new method to form SLB arrays by first forming spherical supported lipid bilayers (SSLBs) on submicrometer-diameter SiO(2) beads. The SSLBs are then arrayed into microwells using a simple physical assembly method that requires no chemical modification of the substrate nor modification of the lipid membrane with recognition moieties. The resulting arrays have submicrometer SSLBs with 3 μm periodicity where >75% of the microwells are occupied by an individual SSLB. Because the arrays have high density, fluorescence from >1000 discrete SSLBs can be acquired with a single image capture. We show that 2-component random arrays can be formed, and we also use the arrays to determine the equilibrium dissociation constant for cholera toxin binding to ganglioside GM1. SSLB arrays are robust and are stable for at least one week in buffer.
