However, there are some potential biases that should be noted. Firstly, the study was conducted at a single center which may limit its generalizability to other populations or settings. Secondly, the sample size of 238 patients may not be sufficient to draw definitive conclusions about the association between cerebrovascular risk factors and collateral compensation in chronic symptomatic IVBS. Thirdly, there is no mention of any potential risks associated with this study such as adverse effects from medications or treatments used during the study period which could affect results. Finally, there is no discussion of possible counterarguments or alternative explanations for the findings presented in this article which could provide a more balanced view on this topic.
