Analysis of Food Extracts with Thin Layer Chromatography: A STEM Outreach Activity.
Article in Journal of chemical education, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
An outreach activity was developed and performed where familiar food items (e.g., beverages, leaves, vegetables, and citrus peels) were extracted with ethanol or ethyl acetate, and the extracts were analyzed through thin-layer chromatography (TLC). The purpose of this activity was to teach participants how chemistry can be used in the real world. Sixteen participants, who were in eighth-12th grade, were divided into four groups with two pairs of individuals. Each group was led by a university student researcher from the advisor's laboratory or by the advisor. The food extracts were analyzed by TLC using solvent systems composed of ethyl acetate and cyclohexane on glass-backed TLC plates with silica gel. After the TLC plates were developed in the solvent chamber, the separated components were visualized using a stain. The pairs of participants repeated the TLC experiment for a second time by choosing their own extracts from different groups to analyze. This outreach activity was deployed at Girls Inc. of San Antonio to show STEM participants how chemistry techniques (extraction and TLC analysis) can be used to separate different compounds from natural sources.
