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

This study investigates how nano-MgO enhances the dynamic properties of lime-stabilized loess, a soil prone to weakening when moistened. Under simulated humidification, the addition of nano-MgO significantly improved the soil's performance: cumulative strain decreased by up to 30.7%, dynamic elastic modulus increased by up to 32.9%, and damping ratio was reduced by up to 19.4%. The high surface activity of nano-MgO accelerates lime-soil reactions, forming a more robust matrix that binds soil particles and fills pores, thereby improving moisture resistance. These findings demonstrate a filler-based strategy for ground improvement, offering a promising approach to mitigate rainfall-induced subsidence and enhance infrastructure stability in loess regions.
