Pig lacks functional NLRC4 and NAIP genes.
Article in Immunogenetics, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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 NLRC4 inflammasome, which recognizes flagellin and components of the type III secretion system, plays an important role in the clearance of intracellular bacteria. Here, we examined the genomic sequences carrying two genes encoding key components of the NLRC4 inflammasome-NLR family, CARD-containing 4 (NLRC4), and NLR apoptosis inhibitory protein (NAIP)-in pigs. Pigs have a single locus encoding NLRC4 and NAIP. Comparison of the sequences thus obtained with the corresponding regions in humans revealed the deletion of intermediate exons in both pig genes. In addition, the genomic sequences of both pig genes lacked valid open reading frames encoding functional NLRC4 or NAIP protein. Additional pigs representing multiple breeds and wild boars also lacked the exons that we failed to find through genome sequencing. Furthermore, neither the NLRC4 nor the NAIP gene was expressed in pigs. These findings indicate that pigs lack the NLRC4 inflammasome, an important factor involved in monitoring bacterial proteins and contributing to the clearance of intracellular pathogens. These results also suggest that genetic polymorphisms affecting the molecular functions of TLR2, TLR4, TLR5, and other pattern recognition receptors associated with the recognition of bacteria have a more profound influence on disease resistance in pigs than in other species.
