[1] Composite Symptoms Scores were computed as the average of Daytime Nasal Scores (Score 0 (best) to 3 (worst)) and Nighttime Symptoms Scores [Score 0 (best) to 3 (worst)].
[2]

Daytime Eye Symptoms scores. Patients were asked to rate each of the 4 eye symptoms of tearing, itchy, red, and puffy eyes daily on a 4-point scale [Score 0 (best) to 3 (worst)].

The average of the 4 individual eye symptoms scores was reported as the Daytime Eye Symptoms Score.

[3]

Daytime Nasal Symptoms Score. Patients were asked to rate each nasal symptom of Congestion, Rhinorrhea, Itching, and Sneezing daily on a 4-point scale [Score 0 (best) to 3 (worse)].

The average of the 4 individual nasal symptoms scores was reported as the Daytime Nasal Symptoms Score.

[4] Nighttime Symptoms Score. Patients were asked to rate each symptom of Nasal Congestion Upon Awakening, Difficulty Going to Sleep, and Nighttime Awakenings daily on a 4-point scale [Score 0 (best) to 3 (worse)], and the average score of the 3 symptoms was reported as the Nighttime Symptoms Score.
[5] Patients completed a Rhinoconjunctivitis Quality-of-Life Questionnaire-28 questions on a 7-point scale [0(best) to 6(worst)] across 7 domains: activity,sleep,non-nose/eye symptoms,practical problems,nasal symptoms, eye symptoms, and emotions. The scores for each domain were averaged, then scores for the 7 domains were averaged for an overall score.

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
The primary efficacy analyses were based on the intention-to-treat (all-patients-treated) principle, i.e., all patients who had a baseline and at least one posttreatment measurement through the first 2 weeks of treatment were included

Reporting Groups
  Description
Placebo Montelukast matching-image placebo tablet and Loratadine matching-image placebo tablet orally once daily in the morning for 4 weeks
