Example 2: Incomplete non-repeating section and one itemset

1—The Form Index column indicates that the non-repeating section appears on two forms for subject AAA, and one form for subject AAB. For subject AAC, the non-repeating section does not contain data. However, its associated itemsets for subject AAC appear in rows 8 and 9.

2—The Itemset Index column indicates that:

• For subject AAA, the non-repeating section is associated with two itemset instances on Form 1 (rows 1 and 2), and three itemset instances on Form 2 (rows 3-5).
• For subject AAB, the non-repeating section is associated with two itemset instances on Form 1 (rows 6 and 7).
• For subject AAC, the non-repeating section is associated with two itemset instances (rows 8 and 9).

3—For subject AAC, the non-repeating section that is associated with Itemset Instance 1 and Itemset Instance 2 does not contain data. Therefore, blank cells appear for the columns that correspond to the data for the non-repeating section.
