诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

肌肉病理呈现典型破碎红纤维以及SSV;基因确诊A3243G的突变。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Muscle pathology shows typical ragged-red fibers;Gene sequence detects A3243G mutation.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

MRI FLAIR images: 血管流空征;高信号血管征。

Index test:

MRI FLAIR images: vessel flow void sign and hyperintensive vessel sign.

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

MELAS:早年卒中样发作;肌肉病理显示典型破碎红纤维;线粒体基因突变A3243G。

例数:

Sample size:

20

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

MELAS:Stroke-like onset at early age, usually before 20 years old; muscle pathology shows typical ragged-red fibers; Gene sequence detects A3243G mutation.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

AIS:卒中样发作年龄较晚;磁共振检查可见典型卒中样病灶。

例数:

Sample size:

20

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

AIS: stroke-like onset at old age after 45 years old;MRI examination demonstrates typical stroke lesions in brain.
