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

The ability of the histidine-rich peptides, histatin-5 (Hst-5) and histatin-8 (Hst-8), to support the generation of reactive oxygen species during the Cu-catalyzed oxidation of ascorbate and cysteine has been evaluated. High levels of hydrogen peroxide (70-580 mol/mol Cu/h) are produced by aqueous solutions containing Cu(II), Hst-8 or Hst-5, and a reductant, either ascorbate or cysteine, as determined by the postreaction Amplex Red assay. When the reactions are conducted in the presence of superoxide dismutase, the total hydrogen peroxide produced is decreased, more so in the presence of the peptides (up to 50%), suggesting the intermediacy of superoxide in these reactions. On the other hand, the presence of sodium azide or sodium formate, traps for hydroxyl radicals, has no appreciable effect on the total hydrogen peroxide production for the Cu-Hst systems. EPR spin-trapping studies using 5-(2,2-dimethyl-1,3-propoxy cyclophosphoryl)-5-methyl-1-pyrroline N-oxide (CYPMPO) in the cysteine-Cu(II) reactions reveal the formation of the CYPMPO-hydroperoxyl and CYPMPO-hydroxyl radical adducts in the presence of Hst-8, whereas only the latter was observed with Cu alone.
