The relationship between ventricular brain ratio (VBR) and clinical variables was investigated in 21 DSM-III depressed patients. None of the following dichotomies--major depression vs. dysthymic disorder, suicidal vs. non-suicidal patients, male vs. female patients--showed any statistically significant differences. An association was identified between VBR and age at onset of depression but when current age was controlled such an association failed to reach a statistically significant level except in the group with major depression. When patients were matched with a control group no differences in VBR were seen with age controlled by decade.
对21名符合《精神疾病诊断与统计手册》第三版（DSM-III）标准的抑郁症患者，研究了脑室脑比率（VBR）与临床变量之间的关系。以下任何二分法——重度抑郁症与恶劣心境障碍、有自杀倾向与无自杀倾向患者、男性与女性患者——均未显示出任何具有统计学意义的差异。VBR与抑郁症发病年龄之间存在关联，但在控制当前年龄后，这种关联除了在重度抑郁症组外，未能达到统计学显著水平。当患者与对照组进行匹配时，按十年控制年龄后，未发现VBR存在差异。
