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
This scoping review investigates the photoprotective efficacy of seed oils from fruits of the Brazilian flora, highlighting their potential as natural sun protection agents. Fourteen experimental studies (2014-2024) were analyzed, covering oils from native or naturalized species in Brazilian biomes (such as Cerrado, Atlantic Forest, Amazon), whose identification and distribution were confirmed through technical records from institutions, such as the Brazilian Agricultural Research Corporation and the Rio de Janeiro Botanical Garden. Some international studies were included, since they investigate species naturalized in Brazil, widely cultivated in the country's biomes. In addition, these studies validate comparative analytical methodologies and highlight the synergistic potential of seed oils with UV filters, making them applicable to the Brazilian context. The formulations tested contained oil concentrations ranging from 1 to 15%, with sun protection factor (SPF) values between 0.22 and 22 for isolated oils and up to 107.67 when combined with organic or inorganic sunscreens. Oils rich in unsaturated fatty acids, tocopherols and polyphenols, such as pomegranate, grape and prickly pear, have shown remarkable absorption of UVB radiation and antioxidant potential. However, methodological limitations such as variations in the extraction process, lack of standardization of formulations, divergences in SPF quantification methods and insufficient safety assessment were identified. Future studies should prioritize the standardization of methods, explore synergistic combinations and validate safety and phototoxicity. It is concluded that seed oils from the Brazilian flora have promising potential as environmentally friendly and effective alternatives for photoprotective formulations.
