Changes in the electroretinograms over time in animals inoculated with US BSE-H.

B-wave amplitude and implicit time in dark-adapted animals with either dim (-20 dB) or bright (0 dB) flash were analyzed over time. Sample size for each time point is in italics. Values in parenthesis are the standard error of the mean. MPI = months post inculcation.* = p ** = p*** = pChanges in the electroretinograms over time in animals inoculated with US BSE-H.对暗适应动物（dark-adapted animals）在弱（-20 dB）或强（0 dB）闪光刺激下的B波振幅（B-wave amplitude）及潜伏时间（implicit time）进行了时序分析。各时间点的样本量以斜体标注。括号内数值为均值标准误（standard error of the mean）。MPI = 接种后月数（months post inculcation）。* 对应p值，** 对应p值，*** 对应p值。接种US BSE-H毒株的动物的视网膜电图（electroretinograms）随时间的变化。
