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

Terahertz spectral analysis is made to study baicalin concentration within scutellaria by enlarging spectral feature. In detail, baicalin powder is added to scutellaria and the change in terahertz spectroscopy is intensified by multiplicative scattering correction and principal component analysis. It is found that multiplicative scattering correction contributes to aligning the first principal components, which allows the prediction of active ingredient ratio with increasing accuracy. The mechanism of feature change is verified from the perspective of spectrum overlapping of independent material. Moreover, by combining the assumption of linear superposition and the algorithm of principal component analysis, the error attached to experiment results is interpreted and attributed to difference between the claimed and actual material component. The study suggests that principal component analysis plays a role in analyzing superposition of independent terahertz spectrum, which is seldom noticed in practice.
