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

Determining the higher order structure (HOS) of proteins and protein complexes is central to understanding their functions, dynamics, and interactions. Traditional structural biology approaches, such as X-ray crystallography and nuclear magnetic resonance, provide high-resolution snapshots but often require large amounts of homogeneous samples and may miss dynamic or heterogeneous states. Mass spectrometry (MS) has become an indispensable tool for sensitive and rapid analysis of intact proteins and assemblies under native or near-native conditions. This review discusses the major MS-based strategies for probing HOS. Native mass spectrometry (nMS) preserves non-covalent interactions and exhibits characteristic charge-state distributions that report on folding, while native top-down fragmentation and ion mobility spectrometry provide sequence-specific and conformation-specific information. Hydrogen-deuterium exchange MS measures backbone amide exchange rates to map regions of solvent accessibility, ligand binding, and allosteric regulation in solution. Covalent labeling MS irreversibly modifies solvent-accessible side chains, allowing epitope mapping and detection of subtle conformational changes, while fast photochemical oxidation of proteins offers microsecond snapshots of transient structures. Chemical cross-linking MS applies bifunctional reagents to capture proximity between residues or subunits, providing distance restraints for integrative modeling and proteome-wide interaction mapping. We outline recent advances in instrumentation, software, labeling chemistry and in-cell techniques across these modalities, and we illustrate their applications to characterizing membrane proteins, large assemblies, therapeutic antibodies, intrinsically disordered proteins, and protein-ligand complexes. Together, these tools offer complementary insights into HOS that are reshaping structural biology, biopharmaceutical development and mechanistic studies.
