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

Hydroxyl radical footprinting (HRF) is a nonspecific protein footprinting method that has been increasingly used in recent years to analyze protein structure. The method oxidatively modifies solvent accessible sites in proteins, which changes upon alterations in the protein, such as ligand binding or a change in conformation. For HRF to provide accurate structural information, the method must probe the native structure of proteins. This requires careful experimental controls since an abundance of oxidative modifications can induce protein unfolding. Fast photochemical oxidation of proteins (FPOP) is a HRF method that generates hydroxyl radicals via photo-dissociation of hydrogen peroxide using an excimer laser. The addition of a radical scavenger to the FPOP reaction reduces the lifetime of the radical, limiting the levels of protein oxidation. A direct assay is needed to ensure FPOP is probing the native conformation of the protein. Here, we report using enzymatic activity as a direct assay to validate that FPOP is probing the native structure of proteins. By measuring the catalytic activity of lysozyme and invertase after FPOP modification, we demonstrate that FPOP does not induce protein unfolding.
