Table 2 Summary of environmental features that show the strongest association with patient BTCP of each deployment when compared with individual BTCP episodes and BTCP frequency/severity over 24 hours
Deployment Number (D.#) | Environmental feature associated with individual episodes of patient BTCP | Environmental feature associated with episodes of patient BTCP over a 24-hour time window | ||
|---|---|---|---|---|
individual BTCP | individual BTCP severity | BTCP frequency | average BTCP severity | |
