Lack of association between plasminogen activator inhibitor type-1 (PAI-1) gene 4G/5G polymorphism and osteoarthritis.
Article in Rheumatology international, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
This study was conducted in Turkish osteoarthritis patients to determine the frequency of 4G/5G polymorphism genotypes of plasminogen activator inhibitor type-1 gene and to examine the role of this polymorphism in osteoarthritis development. Genomic DNA obtained from 200 persons (140 patients with osteoarthritis and 60 healthy controls) was used in the study. DNA was amplified by polymerase chain reaction using 4G allele- and 5G allele-specific primers. Polymerase chain reaction products were assessed with CCD camera by being exposed to 2% agarose gel electrophoresis. No statistically significant difference between the groups with respect to genotype distribution was found (P > 0.05) in the study. The 4G allele frequency was indicated as 44% and 5G allele was as 56% in patients, whereas this was 45-55% in the control group. This study has established that 4G/5G polymorphism genotypes of plasminogen activator inhibitor type-1 gene do not play a role in the development of osteoarthritis in the Turkish population.
