Protocol for a randomised, multicentre, four-arm, double-blinded, placebo-controlled trial to assess the benefits and safety of iron supplementation with malaria chemoprevention to children in Malawi: IRMA trial.
Article in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionApproximately 40% of children aged 6-59 months worldwide are anaemic. Iron-containing multiple micronutrient powders (MNPs) and iron supplements (syrup/drops) are used to combat anaemia in children in different parts of the world. However, evidence for functional benefits of iron supplementation in children is scarce, and potential risks remain poorly defined, particularly concerning diarrhoea and malaria. This trial aims to determine if: (1) the efficacy of iron supplements or MNPs (containing iron) given with malaria chemoprevention is superior to malaria chemoprevention alone, or (2) if the efficacy of malaria chemoprevention alone is superior to placebo on child cognitive development. METHODS AND ANALYSIS: IRMA is a four-arm, parallel-group, double-blinded, placebo-controlled, triple-dummy, randomised trial in Southern Malawi. The study recruits 2168 infants aged 6 months, with an intervention period of 6 months and a post-intervention period of a further 6 months. Children are randomised into four arms: (1) No intervention (placebo); (2) malaria chemoprevention only; (3) MNPs and malaria chemoprevention; and (4) iron syrup and malaria chemoprevention. The primary outcome, cognitive development (Cognitive Composite Score (CogCS)), is measured at the end of the 6 months intervention. Secondary outcomes include CogCS at a further 6 months post-intervention, motor, language and behavioural development, physical growth and prevalence of anaemia and iron deficiency. Safety outcomes include incidence of malaria and other infections, and prevalence of malaria parasitaemia during and post-intervention period. ETHICS AND DISSEMINATION: The trial is approved by the National Health Sciences Research Committee (#19/01/2213) (Malawi) and the Human Research Ethics Committee (WEHI: 19/012) (Australia). Written informed consent in the local language is obtained from each participant before conducting any study-related procedure. Results will be shared with the local community and internationally with academic and policy stakeholders. TRIAL REGISTRATION NUMBER: ACTRN12620000386932.
