Genetic variants of transferrin in cystic fibrosis.
Article in Journal of inherited metabolic disease, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundGenetic polymorphism of serum transferrin (Tf) was studied in order to differentiate between protein genetic variants and congenital disorders of glycosylation (CDG), further focusing on unusual findings.
methodsScreening of Tf hypoglycosylation was carried out by isoelectric focusing with direct immunofixation and Coomassie blue staining in 100 healthy controls and a group of 1247 patients with various symptoms and diagnoses.
resultsOf the seven different genotypes detected, a significantly higher (p = 0.004) frequency of Tf C1C2 was found among 92 patients with cystic fibrosis; only the most severe DF508 mutation (in either homozygous or heterozygous form) was regularly present in the carriers of this Tf genotype, in contrast to those with the Tf C1C1 variant.
conclusionsAssociation of Tf C2 allele with various malfunctions has been noticed before, but is so far unresolved. This is the a report on increased frequency of Tf C1C2 genotype found in cystic fibrosis. Analysis of larger samples and independent confirmation of our results are needed.
