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
Seaweeds represent an excellent vegetable protein resource capable of supporting the objectives of the sustainable blue economy. Today, attention toward algae is growing, due to their applications, both in biofuel production and as an alternative source of healthy food and nutraceuticals. The objective of this work was to valorize marine macroalgae coming from the Mediterranean area in order to be able to expand their potential use in the nutraceutical and pharmaceutical industries, maintaining the circularity of financial and biological resources. Micronutrients with higher antioxidant activity were determined in 10 samples, specifically four red algae, four brown algae, and two green algae. In particular, vitamin C was analyzed using a reversed phase (RP)-HPLC system coupled to photodiode array (PDA) detection, following extraction with an acidified aqueous solution. Vitamin E analysis was performed using a normal-phase HPLC system, following extraction with n-hexane and taking advantage of the high selectivity and sensitivity of fluorescence detector. Vitamin B12 was extracted with an acidified solution of methanol and water and analyzed by RP-HPLC system coupled to PDA and MS, the latter operated under selected ion monitoring mode to increase instrumental sensitivity and selectivity. Finally, carotenoids and pigments were extracted with an acetone/methanol solvent mixture and analyzed by RP-HPLC system coupled to PDA and MS to exploit the complementarity between MS and UV spectra for identification purposes. Overall, the validated HPLC methods confirmed the presence of vitamin E in all the samples analyzed, with highest levels obtained in two brown algae, namely, Undaria pinnatifida (1.54 ± 0.08 mg/kg) and Himanthalia elongata (0.93 ± 0.02 mg/kg), whereas vitamins C and B12 were detected only in two macroalgae species, including the widely consumed Porphyra sp., commercially known as Nori. Finally, carotenoids were mainly determined in the largely consumed U. pinnatifida sample, commercially known as Wakame.
