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.
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
The visible spectra of forty-five synthesized polyaluminium ferric chloride (PAFC) aqueous solutions with different [OH]/[Al + Fe] (B) and nAl/nFe(molar ratio) were investigated. The results showed that their absorbances A of shoulder at 460 nm are all linear interrelationship with their B. We made the curve of absorbance A of PAFC with same B vs. nAl/nFe, there was a turning point. All of these points just located at the places of pH value rising higher in pH- nAl/nFe diagrams. For these reason, we thought that these points stand for the dynamic equilibrium of OH- between the polynucleus hydroxyl Fe(III) and Al(III). These points made certain relationship among the absorbance A at 460 nm, basicities and total Fe(III) concentration of PAFC solutions.
