Efficacy and safety of a house dust mites allergoid in patients with allergic rhinitis-PROACAROS study: protocol for a randomized controlled trial.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThere is an important heterogeneity of the clinical research done to date for allergen immunotherapy (AIT). We plan to assess the safety and efficacy of a house dust mite (HDM) polymerized allergen extract mixture for allergic rhinoconjunctivitis (AR) according to both the EMA and European Academy of Allergy and Clinical Immunology (EAACI) guidelines for the clinical development of products for the treatment of AR.
methodsWe will perform a double-blind, placebo-controlled, randomized parallel group phase III clinical trial to assess the clinical efficacy and safety of a polymerized Dermatophagoides pteronyssinus and Dermatophagoides farinae allergen extract mixture (Beltavac®) to treat perennial AR in children and adults. Patients with moderate or severe rhinitis symptoms, either associated or not with asthma and confirmed HDM sensitization and without relevant concomitant conditions that may interfere with the planned evaluations test are eligible. Patients will be randomized in a 1:1 ratio to either the active AIT or placebo. The experimental group will receive 12 monthly AIT doses via subcutaneous route with a potency of 2 RC/ml per allergen. The expected sample size is 250 patients from 16 sites in Spain. The main efficacy outcome is the Combined Symptom and Medication Score (CSMS) for rhinitis. It will be patients' self-assessed and collected through a phone App developed ad hoc for the study to improve the patient adherence and the quality of data. Main secondary outcomes include expanded CSMS for rhinoconjunctivitis symptoms, control of rhinitis, specific IgE and IgG DISCUSSION: This phase III clinical trial will be of interest to contribute to the scientific evidence about the efficacy and safety of AIT with allergoids. Our working hypothesis is that the investigational product in patients with AR associated or not with asthma is superior to placebo in providing a clinically significant improvement according to the standards defined by the EAACI. This trial will also supply valuable information about patients reported outcomes using health technology for rhinoconjunctivitis and asthma assessment.
