Do we have any study on is breath pattern between aphantasia and non aphantasia person?

Hi fellow fighters, First tell me about my self, My name is Buchibabu. Last year i found my self having aphantasia. I always struggled to get events/ images in my mind and found i have aphantasia. From last more than year, i am practicing mediation where i have to focus just on breath. Many fellow meditators focus on breath easily. but i am unable to find just simple inhale and exhale and my breath pattern also shaky and i just observe inhale, not exhale. I just want to know from fellow community members. How is your breath pattern. Are you able to observe your inhale and exhale? To get this, close your eyes for few mins and just observe your inhale and exhale. Please let me know you answers. we can ask medical community to look in this.
