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

Serial femtosecond crystallography (SFX) enables structural determination of biological macromolecules at room temperature using ultrashort X-ray pulses from an X-ray free-electron laser, thereby minimizing radiation damage and capturing dynamic structural changes. Efficient sample delivery is essential for collecting many diffraction patterns. The grease matrix injection method reduces sample consumption but may encounter nozzle clogging and unstable flow when the crystal size is large, the crystal density is high, or the viscosity of the crystallization buffer-grease mixture increases. Fixed-target approaches, in which crystals are dispersed on a support film, offer a stable alternative with lower sample consumption. Here, we present an optimized fixed-target system integrating a grease matrix and a large-area support film, enhancing sample stability, data collection efficiency, and structural resolution while enabling potential hydrogen atom detection in SFX experiments.
