There was inconsistency in age partitioning and length of age intervals. Meta-analysis was conducted on 13 studies reporting RIs and 2 studies reporting RCs. Pooled estimates for the 0–3 months age group could not be generated for males or females due to paucity of data. For children aged 3 months or older, both lower and upper RI limits generally increased with age, from approximately 100 to 130 g/L and from approximately 130 to 150 g/L, respectively. For visualisation of our narrative synthesis of all 48 studies, we created a novel web-based computational tool using Shiny-app. Sources of heterogeneity included child age, sex, analyser type and country. For many studies, the lower RIs were substantially different from WHO anaemia thresholds.
