Pneumonia remains the commonest cause of ill health and mortality among children worldwide. Severe undernutrition increases the mortality risk among children with pneumonia. While children with pneumonia are at increased risk of developing malnutrition, the impact of pneumonia on mortality and nutritional status of non-severely undernourished children is not well described. The impact of nutritional supplementation on mortality and nutritional status in this population is not well understood. This review will collate available evidence on the all-cause mortality, nutritional (anthropometric) outcomes following pneumonia, as well as the impact of nutritional supplementation on mortality and anthropometry among non-severely malnourished children with pneumonia. The review will be done using criteria developed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. Data will be obtained from data bases, grey literature, and bibliographies. An experienced librarian will conduct article search in PUBMED, MEDLINE, EMBASE, Web of Science, Google scholar, and Scopus. Retrieved articles will be entered in Endnote 9.0, duplicates removed, and transferred to Epi-reviewer for screening and data abstraction. Risk of bias in the included articles will be assessed using standard criteria. Heterogeneity will be assessed using I -statistic and sub-group analysis will be done. Data will be analysed using both narrative and quantitative synthesis. Quantitative synthesis will be done using DeSimonian and Laird Random-effects model in STATA 15.0. The results will provide baseline information about the mortality and nutritional (anthropometric) outcomes of pneumonia among non-severely malnourished children as well as the potential effect of nutritional supplementation on these outcomes. This will provide a basis to explore the potential for nutritional supplementation improving clinical outcomes like mortality and occurrence of severe acute malnutrition among children with severe pneumonia worldwide. The review has been registered in PROSPERO ( CRD42021257272; 15 July 2021).
