Antibody to Haemophilus influenzae type b (Hib) polysaccharide (PRP) was measured in 42 children with acute lymphoblastic leukaemia (ALL) and 42 non-leukaemic hospital controls. Modelling anti-PRP concentrations as a function of age revealed that the slopes of the trend lines differed significantly between cases and controls (P = 0.05); anti-PRP concentrations were lower among younger cases, and higher among older cases, than among controls of the same ages.
在42名急性淋巴细胞白血病(ALL)患儿和42名非白血病住院对照儿童中检测了抗b型流感嗜血杆菌(Hib)多糖(PRP)抗体。将抗PRP浓度作为年龄的函数进行建模,结果显示病例组和对照组的趋势线斜率存在显著差异(P = 0.05);与相同年龄的对照组相比,年龄较小的病例组抗PRP浓度较低,年龄较大的病例组抗PRP浓度较高。
