Sumario: | INTRODUCTION: Meta-analysis is the cornerstone of robust biomedical evidence. OBJECTIVES: We investigated whether statistical reporting practices facilitate metabolomics meta-analyses. METHODS: A literature review of 44 studies that used a comparable platform. RESULTS: Non-numeric formats were used in 31 studies. In half of the studies, less than a third of all measures were reported. Unadjusted P-values were missing from 12 studies and exact P-values from 9 studies. CONCLUSION: Reporting practices can be improved. We recommend (i) publishing all results as numbers, (ii) reporting effect sizes of all measured metabolites and (iii) always reporting unadjusted exact P-values.
