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
backgroundThe neonatal Fc receptors (FcRn) mediate the transfer of immunoglobulin G (IgG) molecules from a dam's circulation to the colostrum produced by it immediately after parturition. In ruminants, the calves born are agammaglobulinemic therefore, ingestion of colostrum with high concentration of IgG imparts passive immunity to the newborn. The FcRn molecule is a heterodimer, coded by FCGRT (Fc fragment of IgG Receptor Transporter neonatal) and B2M (Beta 2 microglobulin) genes. Present study attempted to identify single nucleotide polymorphisms (SNPs) in the FCGRT gene in 40 buffaloes of Murrah breed and evaluated the association of these nucleotide variations and haplotypes with IgG concentration in their colostrum. METHODS AND
resultsAnimals producing colostrum with high IgG and low IgG levels were identified by indirect ELISA and selected. SNPs were detected in the FCGRT gene sequence of selected animals by amplifying it in nine fragments covering all exons (with flanking introns) followed by PCR-single strand conformational polymorphism (PCR-SSCP). A total of nine SNPs were observed of which seven were present in flanking introns and two in exon 4 of the gene. The SNP A75G was non-synonymous and produced an amino acid change from isoleucine to valine. The exonic SNPs and corresponding haplotypes were found to be significantly (P < 0.01 and 0.05 respectively) associated with colostral IgG concentration based on Odds ratios at 95% confidence interval.
conclusionPolymorphism in FCGRT gene is found to be associated with IgG concentration in colostrum and identification of females with desirable variations may prevent failure of passive transfer in neonatal ruminants.
