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
Intestinal fatty-acid-binding protein (IFABP or FABP2) is a cytosolic transporter of long-chain fatty acids, which is mainly expressed in cells of intestinal tissue. Fatty acids in teleosts are an important source of energy for growth, reproduction, and swimming and a main ingredient in the yolk sac of embryos and larvae. The fabp2 paralogs, fabp2a and fabp2b, were identified for 26 teleost fish species including the paralogs for the two non-model teleost fish species, namely the gilthead sea bream (Sparus aurata) and the European sea bass (Dicentrarchus labrax). Despite the high similarity of fabp2 paralogs, as well as the identical organization in four exons, paralogs were mapped to different chromosomes/linkage groups supporting the hypothesis that the identified transcripts are true paralogs originating from a single ancestor gene after genome duplication. This was also confirmed by phylogenetic analysis using fabp2 sequences of 26 teleosts and by synteny analysis carried out with ten teleosts. Differential expression analysis of the gilthead sea bream and European sea bass fabp2 paralogs in the intestine after fasting and refeeding experiment further revealed their altered implication in metabolism. Additional expression studies in seven developmental stages of the two species detected fabp2 paralogs relatively early in the embryonic development as well as possible complementary or separated roles of the paralogs. The identification and characterization of the two fabp2 paralogs will contribute significantly to the understanding of the fabp2 evolution as well as of the divergences in fatty acid metabolism.
