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

To evaluate phosphate-binding by calcium succinate and combinations of calcium and magnesium salts, ion chromatography (IC) methods were developed and validated for the determination of calcium and magnesium across the pH range in the human gastrointestinal tract (pH 1.2-6.8). Separation was achieved on a Dionex IC system using a Dionex IonPac CS12A column. Cations were eluted using 31 mM methanesulfonic acid and detected by suppressed conductivity. A method for calcium was validated according to USP Category 1 requirements and was applicable from 0.5 to 20 μg/mL calcium in 0.1 N HCl; 0.1 N acetate buffer, pH 4.5; or 0.1 N borate buffer, pH 6.8. A method for magnesium was validated independently and found applicable from 0.5 to 20 μg/mL magnesium in 0.1 N acetate buffer, pH 4.5 or 0.1 N borate buffer, pH 6.8. The validated method was successfully applied for the determination of phosphate-binding by calcium succinate and calcium acetate over the pH range found in the human gastrointestinal tract, and for monitoring the release of calcium succinate from encapsulated formulations. The validated method for calcium and magnesium was successfully used to determine phosphate-binding by combinations of calcium and magnesium salts in acetate or borate buffer solutions.
