Though we mapped the data successfully as per OMOP CDM format for few of our tables, we couldn’t understand why Tree Graph in atlas doesn’t pull the hierarchy? For example, we have mapped ‘Simvastatin’ drug and atlas generates all the related hierarchies and displays them in the Treemap as shown in screenshot attached whereas the same doesn’t happen for ‘Anal Abscess’ condition under condition table. Similarly for potassium drug as well
Please note that all the records in condition table are displaying ‘NA’ in hierarchy fields under Tree Map
Can you please help me understand as to what is happening?
