The fresh diamond revealed at the end of your figure ways the new pounds of squares. Brand new horizontal diameter of your diamond shows the new it is possible to range of incidence consequences. One or two vertical outlines receive about shape. The brand new dotted straight line which is in accordance with the diamond vertical axis reveals the general meta-research result (pooled prevalence). Frequency from undesirable maternity and its 95% depend on interval certainly Iranian females based on term off earliest author and 12 months out of analysis using the arbitrary consequences design. The center point each and every range section suggests the incidence away from unwelcome pregnancy into the for each study, and diamond suggests the overall frequency from undesirable maternity
