1 · What the graph read from it

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.

2 · The registry

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

aimsAcute wheezing illnesses are among the most common reasons preschool-aged children are admitted to hospital. Readmission rates are high, and novel preventive strategies are required. OM-85 is an orally administered bacterial lysate that stimulates anti-viral immune responses and reduces excessive airway inflammation associated with wheezing episodes. The aim of the Assessing the Reduction of Recurrent admissions using OM-85 for the treatment of preschool Wheeze (ARROW) trial is to determine the efficacy of OM-85 in preventing hospital readmissions in children admitted to hospital with preschool wheeze. The primary outcome is hospital admission due to an acute wheezing illness during the 12-month treatment period. Secondary outcomes include the frequency and duration of wheeze episodes and the cost-effectiveness of the intervention.

methodsARROW is a decentralised, Phase 3 randomised, double-blind, placebo-controlled trial. We aim to recruit and follow-up 870 children aged 1 to < 6 years. Participants are randomised to 3.5 mg of OM-85 or placebo daily for the first 10 days of every month, for 12 months. Health professionals from over 40 hospitals participating in the Children's Inpatient Research Collaboration of Australia and New Zealand (CIRCAN) invite families to the ARROW trial. The ARROW central team organises enrolment, randomisation, medication distribution, and follow-up, conducting these activities entirely remotely in Australia and both remotely and in-person in New Zealand. ETHICS AND DISSEMINATION: ARROW received ethics approval from The Royal Children's Hospital Human Research Ethics Committee in Australia and the Health and Disability Ethics Committee in New Zealand. Findings will be published in peer-reviewed international journals.
