Batch Effects Removal of GSE22255 and GSE16561. (A) Box plot of Combined GEO Datasets distribution before batch removal. (B) Post-batch integrated GEO datasets (combined datasets) distribution box plots. (C) PCA plot of the datasets before debatching. (D) Go to the PCA map of the combined GEO datasets after batch processing. PCA, Principal Component Analysis; IS, Ischemic Stroke. GSE16561 is the IS dataset in light green, and GSE22255 is the IS dataset in light brown.
