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

Engineering hybrid surface architectures that couple corrosion resistance with biological functionality is critical for extending the performance envelope of biodegradable magnesium-based systems. In this study, a plasma-derived ceramic-metal hybrid coating was engineered on a multicomponent magnesium alloy using plasma electrolytic oxidation (PEO) with controlled incorporation of bismuth species. Sodium bismuthate (1 and 5 g/L) was introduced into a phosphate-alkaline electrolyte, enabling plasma-assisted in situ formation of a multiphase composite coating comprising a MgO/Mg
