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

Developing structural materials with ultrahigh-temperature capabilities is crucial for aerospace and energy applications, yet achieving a balance of strength, heat-softening resistance, and plasticity remains challenging. Here, we report a tungsten-based W-Re-Os alloy with exceptional mechanical properties up to 1400 °C. Utilizing multi-principal element alloy design principles, three refractory metals with melting points above 3000 °C-W, Re, and Os elements are alloyed using combinatorial additive manufacturing. This approach enabled rapid fabrication of ~500 compositions in a single run. High-throughput micro-indentation testing identified W
