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

A simple, sensitive and precise high-performance liquid chromatographic formulations assay for pravastatin (PVS) is described. Good chromatographic separation was achieved using a Teknokroma C8 (5 μm, 25cm × 4.6mm) column and a mobile phase consisting of 10mM ammonium acetate: methanol: triethylamine (40:60:0.17 v/v/v) while at a flow-rate of 1.0 mL min(-1). PVS was detected at 239 nm and was eluted 2.15 min after injection. No endogenous substances were found to interfere. No internal standard was required. Linearity range for PVS was 0.4-1000 μg mL(-1). The determination of intra- and inter-day precision (RSD) was less than 2.94 and 2.97%, at all concentration levels. Statistical treatment of the experimental results indicates that the method is precise and accurate. The proposed method was applied to the determination of the component in commercial tablets with no interference from the excipients. A comparative study between the suggested procedure and the pharmacopoeial method for this compound in the tablets showed no significant difference between the two methods.
