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

Shock waves are ubiquitous in star-forming regions, protoplanetary disks, and cometary environments, yet their role in processing refractory metals remains poorly understood. Here, we show that laboratory shock-tube experiments produce nanophase Fe-Ni alloy from Fe and Ni powders under conditions resembling low-velocity (1-2 km/s) dust-heating shocks in the interstellar medium and cometary comae. The reflected-shock temperature exceeds 6000 K, and pressures reach around 14.5 bar, persisting for about 2-3 ms and completely vapourising the metal powders into an atomic vapour. Subsequent rarefaction drives a catastrophic thermal quench at ∼10
