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
backgroundNeonatal Fc receptors (FcRn) mediate the transcytosis of IgG present in colostrum across absorptive gut epithelium of newborn calves. FcRn receptor is a heterodimer composed of two polypeptides encoded by FCGRT (Fc fragment of IgG Receptor Transporter neonatal) and B2M (Beta 2 microglobulin) genes. Polymorphism in FCGRT gene may have a bearing on absorption of colostral immunoglobulins by neonatal buffalo calves, thereby affecting their immune status and susceptibility to diseases. The primary aim of our study was to mine alleles and single nucleotide polymorphs in the FCGRT gene and determine their association with the levels of IgG in serum of neonatal buffalo calves. METHODS AND
resultsOn the basis of serum IgG levels estimated by indirect ELISA in 80 newborn calves, 20 calves each with highest and lowest IgG concentration were selected to study polymorphism in the FCGRT gene. The exonic regions of this gene were amplified in nine fragments which were subjected to PCR-SSCP to detect variations followed by the sequencing of variants to locate the SNPs. A total of nine SNPs (7 in introns and 2 in exons) were detected in four polymorphic fragments. Association study based on Odds ratios (ORs) with 95% Confidence Interval (CIs) established that the SNP G40T in fragment 3 has a significant (P < 0.05) bearing on IgG level in serum of neonatal buffalo calves.
conclusionGenetic variation in FCGRT gene in buffalo calves was found to be associated with their serum IgG levels in neonatal stage which may have implications in calf survival and growth vis-à-vis inadequate transfer of passive immunity.
