Eligibility

Inclusion Criteria:

• Treatment with ingenol mebutate gel in the treatment area within the last 12 months

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With Complete Clearance of Actinic Keratosis (AK)	The number of clinically visible actinic keratosis lesions (AKs) identified in the treatment area was recorded at Day 1 (baseline), Week 4 and Week 8.; Complete clearance was defined as no clinically visible AKs in the treatment area.	At Week 8
Secondary	Percentage of Participants With Partial Clearance of AKs	Partial clearance was defined as at least 75% reduction from baseline in the number of clinically visible AKs in the treatment area.	At Week 8
Secondary	Percentage of Participants With Partial Clearance of AKs	Partial clearance was defined as at least 75% reduction from baseline in the number of clinically visible AKs in the treatment area.	At Week 4
Secondary	Percent Reduction in AK Count in the Treatment Area Compared to Baseline	The percent reduction at Week 8 from baseline was analysed using a negative binomial regression for the AK count at Week 8 with treatment group and pooled sites as factors and baseline count as offset variable. The table presents adjusted mean percent reduction at Week 8 from baseline.	At Week 8
