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

Q460 steel with varying Ni contents was produced via the hot continuous rolling process. The microstructure and properties were examined using scanning electron microscopy (SEM) and universal testing machines. The results show that with increasing Ni content, the number of inclusions rises, and the microstructure gradually evolves from ferrite and pearlite to a mixture of ferrite, pearlite, and bainite. Due to the formation of bainite and refined grains, both the yield strength and tensile strength are significantly improved. However, with the increase in inclusions, the elongation and impact energy of the material do not exhibit substantial enhancement. Considering both cost and performance, the Ni content in Q460 steel is preferably controlled at 0.3%.
