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

We developed a convenient and simple reversed-phase high-performance liquid chromatographic (RP-HPLC) method for analysis of iodide in concentrated chloride springs. Using a C18 column, the iodide and chloride peaks were well separated. Setting the wavelength at 240 nm allows direct ultraviolet (UV) detection of iodide without any UV or Schlieren effect due to the high chloride concentration. The high ionic strength of spring samples containing high levels of sodium chloride broadens the iodide peak. Iodide was quantified based on the peak areas of standard solutions of iodide, in which 100 mM sodium chloride was added to match the saline matrixes with the samples. The detection limit of iodide at a signal-to-noise ratio of 3 was 0.0003 mM. The detector response was linear over the concentration ranges of 0.001-0.1 mM. The proposed RP-HPLC/UV method was successfully applied to determine iodide in some concentrated chloride spring samples.
