Background: Neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR) and platelet-lymphocyte ratio (PLR) have a prognostic value in several types of diseases such as cancers and they vary in different races. So, we aimed to evaluate the normal range of these markers among healthy people to determine the normal value in Iranian population. Methods: In the present study, cross-sectiona...

An indicator of bypassing is a premature drop in gas-oil ratio; i.e., earlier than expected collapse of gas saturation. Early gas collapse (water fillup) may indicate that channeling has occurred. In layered reservoirs with no or little vertical crossflow, water injection in an initially depressurized layer will cause GOR to drop rapidly. Often naturally fractured reservoirs exhibit fast gas co...

Odds ratio (OR) is a statistic commonly encountered in professional or scientific medical literature. Most readers perceive it as relative risk (RR), although most of them do not know why that would be true. But since such perception is mostly correct, there is nothing (or almost nothing) wrong with that. It is nevertheless useful to be reminded now and then what is the relation between the rel...

background: the superiority of either of body mass index (bmi), waist circumference (wc), waist-to-hip ratio (whr) and waist-to-height ratio (whtr) for prediction of metabolic syndrome (mets) is remained controversial in asian population. the objective of this study was to compare the discriminative capacity of either of these measures in prediction of non-adipose components of mets. methods: i...
