The complete systematic review platform. Search 9 databases, screen studies, extract data, assess risk of bias, run GRADE-compliant meta-analysis, and generate publication-ready figures — all in your browser.
✓ Trial account · 1 project · All analytical features included
A traditional systematic review takes months across disconnected tools — spreadsheets for screening, R for analysis, Illustrator for figures. Verflux integrates every step. Researchers using Verflux complete their reviews in days, not months.
Every feature in every plan. No modules, no add-ons.
PubMed, Scopus, Europe PMC, CrossRef, OpenAlex, Google Scholar, and Web of Science. Boolean operators, year ranges, study-type filters. Cross-database duplicate detection.
Title/abstract and full-text stages. Bulk decisions, keyboard shortcuts, abstract viewer. Blind dual-reviewer mode with conflict resolution.
Arm-level extraction for continuous and dichotomous outcomes. Auto-fill from DOI or PMID. Unlimited outcomes per study.
RoB 2, ROBINS-I, Newcastle-Ottawa Scale, QUADAS-2, AXIS. Domain-level traffic-light ratings with overall judgement.
Certainty ratings per outcome. Five downgrade and three upgrade domains. Evidence summary table auto-generated.
DL and PM random effects, fixed-effect IV. Hedges g, subgroup analysis, leave-one-out sensitivity, Egger test.
Forest plot with weight-proportional squares and prediction intervals. Funnel plot with confidence region. High-DPI PNG download.
Correct three-phase flow diagram. Every value editable with live preview. Saves per project. PNG download.
Every other tool requires R, Python, or expensive software licenses. Verflux runs in your browser and handles the entire pipeline end-to-end.

"I completed a 61-study meta-analysis in under a week. What used to take months of juggling PubMed, Excel, and R now happens in one browser tab. The forest plots are publication-ready straight out of Verflux."
"The GRADE assessment and PRISMA 2020 flow diagram generation saved me enormous time. The statistical output matches what I get from R metafor, but I don't need to write a single line of code."
"Finally a tool that handles dual-reviewer screening AND meta-analysis in one place. The conflict resolution queue is brilliant. Highly recommend for any research team doing evidence synthesis."
