Leptin gene tetranucleotide repeat polymorphism in obese individuals in Egypt.
Article in International journal of health sciences, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundLeptin is a peptide hormone secreted by the adipose tissue. Genetic mutations of the leptin gene were reported to cause severe obesity.
objectivesThis study was undertaken to investigate the association of the polymorphic tetranucleotide repeat locus 3' UTR of leptin gene with obesity in Egyptian cases. SUBJECTS AND
methodsThis study has included 120 subjects affected with obesity 57 of them were consistent with the diagnosis of metabolic syndrome (MS) while the rest (63) had simple obesity. These cases were compared to 83 normal weight healthy controls. All participants were subjected to an estimation of their body mass index (BMI), waist hip ratio (WHR), serum as well as characterization of leptin gene tetranucleotide repeat (TTTC)n polymorphism by PCR technique.
resultsThirteen different alleles were identified in all cases of obesity versus only 5 alleles in normal controls. The most frequent allele was the 154 bp allele (57.5% in all cases of obesity vs. 92.2% in controls). Total cases with obesity showed a significantly higher carriage rate of class II alleles (I/II + II/II genotypes) compared to healthy controls (48.3% vs. 6.0%, OR=14.6, 95% CI=5.5-38.6, p=<0.0001). This was more apparent in the group with simple obesity (52.3% vs. 6.0%, OR=17.2, 95% CI=6.1-48.1, p=<0.0001) than in MS cases (43.9 % vs. 6.0 %, OR =12.19, 95% CI=4.9-30.4, p=< 0.0001). Interestingly, cases with MS did not differ from those with simple obesity regarding their class I or II allele frequencies (p> 0.05). Although serum lipids were significantly higher in obese cases compared to controls, no difference was found among obese cases with different leptin gene class genotypes (p> 0.05).
conclusionsTetranucleotide repeat (TTTC)n polymorphism in the 3' UTR of the human leptin gene was associated with obesity in Egyptian obese cases showing higher class II allele carriage rate. However, the lipoprotein levels were not affected by this polymorphism.
