Projects where method changed the decision
Each case study sets out the real problem, the methodological decision that solved it and how far the conclusion goes. No inflated figures, and no taking credit for what we did not do.
Health research
Anonymisation and traceability of data in a population health databaseHow we turned manual anonymisation into a standardised, reproducible and traceable process for the Servicio Navarro de Salud-Osasunbidea, the regional health service of NavarreRead case study →Validation of a risk perception questionnaire on handling hazardous drugsPsychometric validation of an instrument that measures perceived risk of exposure to hazardous drugs among healthcare professionals, with a comparison of perception across professional groupsRead case study →Survival analysis of joint implants in a regional registryKaplan-Meier, Cox models and Fine-Gray competing risks to assess implant durability over more than a decade of population follow-upRead case study →Implementation science in community pharmacyAnalysis of barrier-cause-strategy flows to scale up a pharmacy service nationallyRead case study →Machine learning for pharmacy triagePredictive models with SHAP explainability to identify high-risk patients in more than 500 community pharmacies across SpainRead case study →The obesity paradox and nutrition in critically ill patientsSurvival analysis and multivariable modelling in a multicentre ICU study to assess obesity, mortality and nutritional supportRead case study →
Nutrition and food health
Farmer characterisation and biofortified maize adoption modellingFrom segmenting producers' current behaviour to projecting who would adopt the biofortified seed, in what order and to what degree as market penetration advances.Read case study →Methodological reanalysis of meta-analyses on biofortified cropsAn independent statistical review with metafor to assess the robustness of the evidence on the effectiveness of vitamin A, iron and zinc biofortificationRead case study →Estimating child dietary intake at national scaleIntegrating two unlinked national surveys to estimate dietary intake in the child population, combining consumption data, anthropometry and vital records through statistical transfer.Read case study →
Public health and epidemiology
Impact of biofortification on chronic child undernutritionEstimating the effect of biofortified maize on child stunting through two distinct analytical pathways that converge on the same result.Read case study →Multilevel simulation engine for the impact of biofortified maizeA tool that simulates, at national and department level, the effect of introducing biofortified maize in Guatemala through two lenses at once: the economic one for farmers and the epidemiological one for chronic child undernutrition.Read case study →Epidemiological surveillance of frailtyA population-wide platform of frailty indicators for public health decision-makingRead case study →Descriptive epidemiology of HPV in the post-vaccination eraGenotype distribution among positive samples in a post-vaccination setting, with an analysis by sample type to inform surveillance and screeningRead case study →Infodemiology of metabolic syndromeAnalysis of population web search behaviour for complementary epidemiological surveillanceRead case study →Topic modelling and NLP on scientific literatureUnsupervised extraction of latent topics from a scientific corpus using topic modelling and sentiment analysisRead case study →
