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 presents a high-precision wireless displacement monitoring microsystem that utilizes the tunnel magnetoresistance (TMR) effect for structural health monitoring (SHM). The system overcomes limitations of traditional SHM methods, providing high-precision, intelligent and lightweight measurements. We established an analytical model of magnetic field displacement and optimized its linear range. Considering the measurement error caused by magnetic field decay, we designed an adaptive sensitivity correction method, thus avoiding the tedious magnetic field numerical fitting process. The system's accuracy and stability are validated through comparison with laser ranging, showing high accuracy within the range of ±7.5 mm, a resolution of 0.4 μm, and a long-term working accuracy better than 2.25 μm. The core system is less than 3.84 cm
