Fig. 1From: An automated data cleaning method for Electronic Health Records by incorporating clinical knowledgeA toy example to show how the fuzzy search method works. The correct possible units for one specific variable are known in CKD. The algorithm compares the raw data and the possible units in CKD and selects one unit that requires a minimum of edits or NA if the scores are below the threshold. (The vector of correct unit is not the full vector in CKD.)Back to article page
