Identification and quantitation of genetically modified (GM) ingredients in maize, rice, soybean and wheat-containing retail foods and feeds in Turkey.
Article in Journal of food science and technology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The cultivation area and diversity of genetically modified (GM) crop varieties worldwide is increasing rapidly. Taking Turkey as an example of a country with tight restrictions on the import and use of GM crops but limited resources for product monitoring, we developed a cost-effective 3-tier screening protocol, and tested 110 retail food products and 13 animal feeds available in 2016-2017 for GM ingredients. No evidence was found for the presence of GM wheat or rice in the foodstuffs tested; however, 6 feeds and 3 food products containing soybean and/or maize were positive for one or more GM elements. GM events present in positive samples were identified by event-specific PCR and quantified by real-time PCR. We also compared the results with previous surveys in Turkey. Overall, we observed consistent use of GM animal feeds; however, these were not labelled as GM at the point of sale. Occasional food products also tested positive for GM ingredients, usually at low concentrations that could be attributed to accidental contamination.
