Limitations and caveats
Due to poor enrollment (even after extending the enrollment period), only 314 participants (not 600 participants) were randomized to the study and hence the study was inconclusive due to the lacking of statistical power and robustness.

Registered outcomes1

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryChange in the Urticaria Activity Score (UAS) From Baseline to the Final Week for Desloratadine 5 mg Versus Desloratadine 20 mgBaseline and 4 treatment weeks
The UAS is a composite diary-recorded score. The diary recorded scores included wheal score and pruritus score with numeric severity intensity ratings of 0 = none to 3 = intense. The scoring was to be done twice daily within one hour of arising and in the evening, approximately 12 hours later. Scoring was "reflective", covering the 12-hour period since the previous recording. The daily UAS is the average of the morning and evening scores. The final week by definition was the terminal week. It was the last week participants stayed for the treatment period.
