Functionalized graphene quantum dots based non-enzymatic sensor for selective tyrosine detection.
Article in RSC advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Tyrosinemia is an inherited metabolic disorder that occurs due to the disruption in the breakdown of the amino acid 'tyrosine'. Elevated levels of tyrosine cause liver failure, and neurological damage in newborns. Hence, rapid and accurate detection of tyrosine is essential for the timely management and diagnosis of this disorder. In this context, a non-enzymatic electrochemical sensor has been fabricated using Graphene Quantum Dots (GQDs) functionalized screen-printed carbon electrode for the detection of tyrosine. The different functional groups present on the surface provides efficient binding and recognition of tyrosine. The electrochemical signatures of the fabricated electrodes exhibited a sensitivity of 0.03 µA µM
