Determination of the main phenolic compounds of olive (Olea europaea L.) leaves by near infrared spectroscopy (NIR).

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.
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 main phenolics compounds in Olea europaea L. leaves are oleuropein, hydroxytyrosol, hydroxytyrosol hexoside, verbascoside and apingenin-7-glucoside, being oleuropein the most abundant. In the literature, there are different methods to determine some of these compounds, which imply an analytical preparation for their determination. In this line, the use of techniques based on infrared spectroscopy is presented as a promising alternative. Therefore, a near-infrared spectroscopy (NIR) calibration, validation and prediction to determine the main metabolites in olive leaves has been developed. To achieve this, olive leaves samples were analysed by HPLC-DAD to quantify the concentrations of the main phenolic metabolites. Subsequently, a predictive model was developed through NIR calibration, achieving a good R
