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

An oral sorbent AST-120 composed of spherical porous carbon particles has superior adsorption ability for certain small-molecular-weight organic compounds known to accumulate in patients with chronic renal failure (CRF). A metabolomic approach was applied to search for uremic toxins as possible indicators of the effect of AST-120. Serum metabolites in normal and CRF rats before and after administration of AST-120 for 3 days were analyzed by liquid chromatography/electrospray ionization-tandem mass spectrometry (LC/ESI-MS/MS) and principal component analysis. Further, serum and urine levels of the indicators were quantified by selected reaction monitoring of LC/ESI-MS/MS. Indoxyl sulfate was the first principal serum metabolite, which could differentiate CRF from both normal and AST-120-administered CRF rats, followed by hippuric acid, phenyl sulfate and 4-ethylphenyl sulfate. CRF rats showed increased serum levels of indoxyl sulfate, hippuric acid, phenyl sulfate, 4-ethylphenyl sulfate and p-cresyl sulfate. Administration of AST-120 for 3 days to the CRF rats reduced the serum and urine levels of these metabolites. In conclusion, indoxyl sulfate is the best indicator of the effect of AST-120 in CRF rats. Hippuric acid, phenyl sulfate and 4-ethylphenyl sulfate are suggested as the additional indicators. 4-Ethylphenyl sulfate is a newly identified uremic substance.
