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 present study was conducted to carry out the phytochemical investigation of Tanacetum gracile Hook. f. & Thomson and to develop a method for the simultaneous quantification of the isolated compounds in the extracts ofT. gracile growing in different locations. Cluster analysis rectangular similarity matrix was performed to understand the chemical fingerprinting variations in the extracts. High-performance liquid chromatography-electrospray ionization-quadrupole-time-of-flight-mass spectrometry (HPLC-ESI-QTOF-MS) was used to quantify four bioactive compounds, and separation of the compounds was achieved on a reverse-phase C8 column using a mobile phase of acetonitrile: 0.1% formic acid in water with a gradient elution by maintaining the flow rate of 300 μL/min. The QTOF-MS was operated using the electro-spray ionization technique with the positive ion polarity mode. The calibration curves of four marker compounds were linear over the concentration range of 3.12-100 ng/µL (R(2)> 0.996). A specific, accurate and precise HPLC-ESI-QTOF-MS method was optimized for the determination of kaempferol, ketoplenolide, tetramethoxyflavone and artemetin both individually and simultaneously. Quantification of these chemical markers in different extracts was carried out using this validated method. Kaempferol was isolated for the first time from T. gracile.
