Conditioned Taste Aversion to L-Amino Acid Taste Stimuli and Oral Transcriptional Changes to Type 1 Taste Receptors T1R1 and T1R3 on Chronic Exposure to L-Alanine Solution in Chickens.

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
Elucidating taste sensing systems in chickens is an important step toward understanding poultry nutrition. Amino acid taste receptors, type 1 taste receptors 1 and 3 (T1R1 and T1R3, respectively), are expressed in chicken taste cells, and chicken T1R1/T1R3 is activated by L-alanine (L-Ala) and L-serine (L-Ser), but not by L-proline (L-Pro). However, it is not clear whether chickens have a gustatory perception of L-amino acids. Here, we found that chickens conditioned to avoid either L-Ala, L-Ser, or L-Pro solutions could successfully learn to avoid the corresponding L-amino acid solution in the conditioned taste aversion (CTA) test. Because CTA is a well-established learning paradigm generated specifically by pairing gustatory perception and gastrointestinal malaise, the present study suggests that chickens can sense L-amino acids by gustatory perception. In addition, we found that the expression of the
