Free PRISMA 2020 and meta-analysis tools

Build a PRISMA 2020 flow diagram that checks your arithmetic, convert effect sizes for meta-analysis, and turn your concepts into search strings for seven database/platform outputs and registry prompts. Calculations stay local. Online MeSH lookup and optional AI send research terms only after you approve.

Enter your numbers as you screen. Grey boxes calculate themselves, and anything that does not add up is flagged before a reviewer sees it. Download as SVG for the manuscript or PNG for slides and posters.

Identification

One row per database, using the count from your search log.

Leave blank if every report is a separate study.

Other methods
Diagram options

Layout follows the PRISMA 2020 flow diagram template (Page MJ, et al. BMJ 2021;372:n71). Your entries are saved in this browser only.

Studies rarely report data the way your meta-analysis needs it. Convert once, record what you did in your extraction notes, and run a sensitivity analysis without the converted studies when the data look skewed.

Free systematic review tools

Guides for each tool: PRISMA 2020 flow diagram generator · effect size converter · systematic review search builder.

InsightMed combines three common evidence-synthesis tasks in one private browser workspace. Outputs remain drafts requiring scientific and information-specialist judgment.

PRISMA 2020 flow diagram generator

Enter identification, removal, screening and inclusion counts. The generator derives totals, flags inconsistent arithmetic and exports SVG or PNG.

Effect-size converter

Convert confidence intervals, change-score standard deviations, medians and spread statistics, standard errors, 2×2 tables and combined groups.

Systematic review search builder

Start with a topic or PICO question, review optional MeSH suggestions and produce editable platform-specific search drafts.

Capabilities and limits

ToolOutputsImportant limitation
PRISMA flow diagramArithmetic checks; SVG and PNGNew reviews only; reconciled counts do not prove compliance.
Effect-size converterEight conversions with validation and source notesDoes not replace statistical review or sensitivity analysis.
Search strategy builderPubMed, Embase, Scopus, Web of Science, CENTRAL and registriesVerify headings and syntax in the live platform.

Methodological basis

The diagram follows the PRISMA 2020 statement and templates. Statistical conversions follow relevant guidance in Cochrane Handbook Chapter 6. Optional MeSH suggestions use NLM NCBI E-utilities.

Frequently asked questions

What tools are included?

A PRISMA 2020 diagram generator, eight statistical converters and a database search strategy builder.

Is this an official PRISMA tool?

No. Compare the final diagram with the official PRISMA template and reporting guidance.

Does InsightMed upload review data?

Core calculations remain in the browser. Approved MeSH or optional AI requests send research terms to the relevant external service.

Can it handle updated reviews?

No. Use the official PRISMA updated-review templates for updated systematic reviews.
