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
This study is to investigate the use of microbial remediation technology for degradation of dexamethasone in polluted water. A strain of Pseudomonas Alcaligenes with the ability of dexamethasone degradation was isolated from hospital polluted water. This strain was further acclimated into a bacterial strain that could highly degrade dexamethasone. Domesticated bacterial proteins were separated by osmotic shock method and were analyzed using SDS-PAGE. Enzyme activity of dexamethasone degradation was detected by high performance liquid chromatography. Protein bands with different molecular weight were found in all regions of the bacteria and a band with molecular weight of about 100 kDa was most obvious. In intracellular and periplasmic liquid, there was a band with molecular weight of about 41 kDa. Enzyme activity mainly existed in intracellular liquid. The 41 kDa protease was purified using ammonium sulfate precipitation, DEAE-52 ion exchange column and Sephadex G-100 column. Dexamethasone and dexamethasone sodium phosphate degrading rates of the purified enzyme were 36% and 95%, respectively. The 100 kDa protein had a 19% coverage rate to TonB receptor dependent protein, with 11 peptides matching. The 41 kDa protein had a 56% coverage rate to isovaleryl coenzyme A dehydrogenase, with 5 peptides matching. The 41 kDa protein had good degradation between the temperature of 25-40°C and PH value of 6.5-8.5. The enzyme kinetics equation was Ct = C0 e(-0.1769t), in accordance with the first-order kinetic equation. This study laid the foundation for further preparation of bioremediation agents for clearance of dexamethasone pollution in water.
