“…The incidence of leukemia in our study showed that Eastern Region ranked second which is might be due to presence of ARAMKO, the largest oil company around the world and Jubail Industrial City, global city for chemical industries. Many reports revealed that Exposure to petroleum, petrochemicals and petroleum oil was strongly associated with leukemia 6,7,8,9 however, further studies are needed to determine whether if this association also occurs in Saudi Arabia. Moreover, there was seldom r eports about the incidence of leukemia in specific region which is Northern region reporting that leukemia ranked sixth among all types of cancers by 26 cases registered in 2002.…”

“…For instance, the observed density of disease patients in each point of space can be divided by the total number of people living in the same location (Kloog et al 2009;Shi 2010;Zusman et al 2012). An additional benefit of this technique, also known as the Double Kernel Density (DKD) estimate, is that it helps to minimize the aforementioned "edge" effect: Since both the events of interest and the general population do not have values outside the study area, the edge effect can be minimized or alleviated by normalization (Gatrell et al 1996;Portnov and Zusman 2014).…”

“…However, such aggregation may result in a modifiable areal unit problem (MAUP), according to which different strength of statistical association may emerge from the analysis of data based on different units of spatial resolution (Openshaw 1984;Portnov et al 2009;Swift et al 2014). An additional problem may also arise if the events of interest are highly concentrated in space, and the overall number of areal units, available for aggregation is small, leading to inconclusive results and low statistical power (Li and Lian 2010;Zusman et al 2012). …”
