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 goal of this study is to use the TLC-densitometric method to determine the concentration of catechin, pyrocatechol, and quercetine in gambir block extracts in a reliable and efficient manner. The best eluent is a mixture of chloroform: ethyl acetate: glacial acetic acid (4:4:2). The concentration of catechin, pyrocatechol and quercetine in gambir block was found to be 25.50 ± 3.13, 0.91 ± 0.60 and 0.83 ± 0.34% (w/w) w/w respectively. The linearity was obtained between 750-2500, 50-350, and 50-350 μg/spot. 12.49-41.63, 0.48-1.60, 3,85-12.83 μg/spots were found to represent the LOD and LOQ, respectively. The proposed approach exhibited great sensitivity, precision, and accuracy, as well as strong linearity.
