Evidence Synthesis Specialist, Network Meta-Analysis, RoB2/ROBINS-I, Clinical Trial Data Extraction

Profile Summary

Profile Summary I am a PhD-trained clinical researcher with 3 years of experience specializing in systematic reviews, network meta-analysis (NMA), and structured evidence synthesis for clinical and regulatory decision-making. My work bridges rigorous methodology and practical, reproducible workflows — from protocol design through data extraction, risk of bias assessment, statistical analysis, and manuscript preparation. Core expertise Systematic reviews and meta-analyses following Cochrane Handbook and PRISMA 2020 standards, including protocol registration (PROSPERO), comprehensive search strategy design, dual-reviewer screening, and GRADE certainty-of-evidence assessment. Network meta-analysis (NMA) in both frequentist and Bayesian frameworks, including assessment of transitivity, consistency, ranking (SUCRA/P-scores), and CINeMA for confidence in NMA estimates. Risk of bias assessment using RoB 2 for randomized trials and ROBINS-I for non-randomized studies, with domain-level justification and sensitivity analyses. Structured data extraction from published trials and ClinicalTrials.gov registrations, including arm-level outcome data, zero-event handling for rare outcomes, and statistical conversions (e.g., median/IQR to mean/SD using Wan et al. 2014). Reproducible analytic workflows with standardized treatment naming conventions, explicit coding of missing data (NR/NS/NE/NA), and output structured for direct ingestion into R (netmeta, meta, metafor) and Stata. Ongoing and recent projects Developing and refining a comprehensive data extraction protocol for GLP-1 receptor agonist trials, designed for full reproducibility across reviewers and sessions. Conducting trial-level data extraction on RCTs of glucose-lowering and weight-loss therapies, integrating published manuscripts with ClinicalTrials.gov outcome data. Designing NMA-ready datasets in long format (netmeta_long) with paired outcomes inventory and trial characteristics tables to support transparent re-analysis. Technical skills Statistical software: R (netmeta, meta, metafor, gemtc, tidyverse), Stata Evidence synthesis tools: Covidence, Rayyan, RevMan, EPPI-Reviewer, GRADEpro Risk of bias: RoB 2, ROBINS-I, ROBIS, AMSTAR-2 Data management: Excel (advanced), structured CSV/long-format datasets, ClinicalTrials.gov data parsing Languages Trilingual: English, Spanish, and French — enabling literature screening, data extraction, and collaboration across major bodies of clinical research literature. Education PhD — UNAM What I offer clients Whether you need a full systematic review conducted from scoping to publication, a focused data extraction effort for an existing review, an NMA built on a transparent and auditable dataset, or methodological consulting on risk of bias or evidence certainty — I deliver work that is reproducible, well-documented, and ready for peer-reviewed publication or regulatory submission.
