Lysine requirements in small, medium, and large breed adult dogs using the indicator amino acid oxidation technique.
Article in Translational animal science, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
There is a lack of knowledge regarding the lysine (Lys) requirements of mature dogs and whether there are breed differences. The present study aimed to determine the Lys requirement in three breeds of mature dogs using the indicator amino acid oxidation (IAAO) technique. Thirteen adult dogs were used, four Miniature Dachshunds (5.39 ± 0.71 kg; 1.05 ± 0.02 yr old, mean ± SD), four Beagles (8.09 ± 0.40 kg; 5.03 ± 0.09 yr old, mean ± SD), and five Labrador Retrievers (29.42 ± 2.04 kg; 3.30 ± 0.69 yr old, mean ± SD). After 14 d of adaptation to a basal extruded kibble diet, dogs were fed a test diet mildly deficient in Lys (Lys concentration = 0.36%) at 17 (Miniature Dachshunds) or 13 g/kg body weight (BW; Beagles and Labradors) for 2 d. The test diet was supplemented with one of seven isonitrogenous Lys-Ala solutions, resulting in a final dietary Lys concentration of 0.36%, 0.40%, 0.44%, 0.50%, 0.54%, 0.58%, and 0.62% (as-fed basis). Dogs received dietary concentrations of Lys in random order and no dog received the same order. Following 2 d of adaptation to the experimental diets, the dogs underwent IAAO studies. During the IAAO studies, total daily feed was divided in 13 equal meals. At the sixth meal, dogs were fed a bolus of L-[1-
