Molecular cloning, tissue expression and association of porcine NR4A1 gene with reproductive traits.
Article in Molecular biology reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Nuclear receptor subfamily 4, group A, member 1 (NR4A1), other aliase NGFI-B, is an immediate-early gene that encodes an orphan nuclear receptor, which play a potential role in the ovulatory process. In this study, a 4,870 bp fragment covered the complete coding region (CDS) and its unique intron sequences of porcine NR4A1 gene was obtained. The reverse transcriptase-polymerase chain reaction (RT-PCR) indicated that NR4A1 was highly expressed in ovary, uterus, kidney, heart but at very low level in oviduct and not expressed in other tissues. Compared the sequence of CDS and its unique intron of Large White and Meishan pigs, a A/G mutation in intron 5 was found and a PCR-Dde1-RFLP genotyping assay was developed. Association of the SNP and litter size was assessed in two populations [purebred Large White and an experimental synthetic Line (DIV) sows]. Statistical analysis demonstrated that, in the first parity, AG animals in experimental synthetic Line (DIV) sows had 1.805 more piglets born compared to the GG animals (P<0.05). For all parities, in the purebred Large White pigs, those with the GG genotype had an additional 0.877 piglets born and 0.780 piglets born alive compared to the AA animals (P<0.05), those with the AG genotype had additional 0.780 piglets born compared to the AA animals (P<0.05). In addition, significant additive effect of 0.438±0.182 piglets/litter and 0.368±0.165 piglets/litter on piglets born and piglets born alive were detected in the purebred Large White lines (P<0.05), respectively. Therefore, NR4A1 gene was significantly associated with litter size in two populations and could be a useful molecular marker in selection for increasing litter size in pigs.
