Table 1 Definitions of the rules generating disease outcomes

Period

1

2.96

At least one Loss exposure event in the first two years of life.

2

2.27

At least two Loss exposure events in the first five years of life.

3

1.68

Weighted sum of Loss exposures exceeds 1. Events in the first two years are unweighted; from age 2–4 are weighted by 0.5; age 5–11 by 0.2; and age 12–15 by 0.1.

Repeats

1

1.37

Four or more consecutive Dynamic exposure events.

2

1.30

At least two instances of two consecutive years of Dynamic exposure events.

3

1.77

At least two consecutive years of both Loss and SES exposure events.

Order

1

5.68

First Dynamic exposure event precedes the first Loss exposure event, with at least one occurrence of each.

2

1.98

First two Dynamic exposure events precede the first Loss exposure event, with at least one occurrence of each.

3

1.80

Similar to Order 1, but the effect is mitigated if SES exposure events occur.

Timing

1

3.10

Loss and SES exposure events occur in the same year at least once.

2

1.11

Loss and SES exposure events occur within one year of each other at least twice.

3

2.50

Loss and SES exposure events occur within four years of each other at least twice.
