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
Haloarcula rubripromontorii BS2, an extremely halophilic archaeon was obtained from the solar salt pans of Goa, India. It grew luxuriantly on EHM medium with 25% NaCl with a bright orange pigmentation. This study aimed to extract and characterize the carotenoids from Haloarcula rubripromontorii BS2 and evaluate their antioxidant properties, biocompatibility and provide insight into their potential therapeutic applications. Preparative high-performance liquid chromatography (HPLC) was employed to fractionate and separate the haloarchaeal carotenoids. Further detailed characterization using liquid chromatography-mass spectrometry (LC-MS), Raman spectroscopy and nuclear magnetic resonance (NMR) spectroscopy for each fraction confirmed the presence of C50 carotenoids primarily bacterioruberin, monoanhydrobacterioruberin, and their different isomeric forms. Our results indicate that these carotenoids are more stable in oil compared to solvents. 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3 ethylbenzothiazoline-6-sulfonic acid (ABTS) assays resulted in an IC
