In a sample of 215 adult males the mean red cell volume decreases linearly with increasing red cell concentration. The mean corpuscular volume and the red cell count are found uncorrelated with age of subject. Of these subjects 69 are identified as smokers and 114 as nonsmokers. Linear regression analysis shows negative linear relation for the smoking-defined groups, with slopes judged to be no different. When the regression lines are constrained to be parallel the line for smokers is displaced upward by 2.7 fl. No difference is found in mean corpuscular haemoglobin concentration or reticulocyte count. Haematocrit, haemoglobin, mean corpuscular haemoglobin are also reported. Viscosity of blood is greater in smokers. Optical determination of cell volume and area confirms the linear relation of volume and count.
在215名成年男性样本中，平均红细胞体积随红细胞浓度增加呈线性下降。平均红细胞体积和红细胞计数与受试者年龄无关。这些受试者中，69人被确定为吸烟者，114人为非吸烟者。线性回归分析显示，按吸烟定义的组呈负线性关系，斜率判断无差异。当回归线被约束为平行时，吸烟者的线向上偏移2.7飞升。平均红细胞血红蛋白浓度或网织红细胞计数无差异。还报告了血细胞比容、血红蛋白、平均红细胞血红蛋白。吸烟者的血液粘度更大。细胞体积和面积的光学测定证实了体积和计数的线性关系。
