Figure 4From: Associations between ghrelin and ghrelin receptor polymorphisms and cancer in Caucasian populations: a meta-analysisForest plot of homozygous pooled effect in the rs4684677 polymorphism. Black diamond denotes the pooled OR. Blue squares indicate the OR in each study, with square sizes directly proportional to the weight contribution (%) of the study. Horizontal lines represent 95% confidence intervals. Note that case-control values for Doecke et al. [10] were non-estimable and therefore not included in the forest plot.Back to article page
