A study on oncogenic role of leptin and leptin receptor in oral squamous cell.
Article in Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
Leptin been mainly produced by adipose tissue and cancer cells is the most studied adipokine, amongst the several cytokines. Leptin is an antiapoptotic molecule and inducer of cancer stem cells as well as activates cell proliferation. Its oncogenic, mitogenic, proinflammatory and proangiogenic actions lead to its vital roles in tumourigenesis. Two common functional DNA polymorphisms in the genes of leptin G2548A (LEP) and leptin receptor A668G (LEPR) affect the amount of circulating cytokine-type hormone leptin with risk for development of oral squamous cell carcinoma (OSCC). The present study investigated whether these LEP and LEPR gene polymorphisms are affecting risk for OSCC by comparing the genotypes of patients with controls. A total of 306 OSCC and 228 controls participated in this study. We have determined the frequency of LEP (G2548A) and LEPR (A668G) gene polymorphisms in OSCC cases and controls by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). The incidence of leptin gene G2548A homozygous mutant AA polymorphism was significantly increased in the OSCC patients (p = 0.002, odds ratio (OR) = 2.4, 95 % confidence interval (CI) = 1.37-4.22) when compared with controls, and leptin receptor A668G homozygous mutant GG polymorphism was significantly high in the OSCC patients as compared to controls (p = 0.000, OR = 3.8, 95 % CI = 1.98-7.62). The polymorphism of homozygous mutant allele A of leptin gene and G allele of leptin receptor may be associated with increased risk for OSCC. The observations showed regular increase of supporting role of leptin in OSCC. The present study showed an association of AA genotype and A allele of LEP G2548A as well as GG genotype and G allele of LEPR A668G polymorphisms with increased risk for OSCC in north Indian patients. Moreover, the combination of both the polymorphisms may be involved in susceptibility and progression of OSCC.
