Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | Female Cases | Female patients with a confirmed diagnosis of Vitiligo within the study period will be included as cases for analysis.~Exposure of skin cancer of interest: Melanoma and nonmelanoma skin cancers: squamous cell carcinoma, basal cell carcinoma and actinic keratoses. | 78 | 8,159 | OG000 | ClinicalTrials.gov |
| Group 2 | Female Controls | The controls will be defined by matching cases with people who have never been diagnosed with vitiligo either prior to or during the study period, by age and sex, at General Practice level.~Exposure of skin cancer of interest: Melanoma and nonmelanoma skin cancers: squamous cell carcinoma, basal cell carcinoma and actinic keratoses. | 429 | 32,121 | OG001 | ClinicalTrials.gov |
