BioClaritas — Systematic Review, Meta-Analysis & Research Automation Platform

The All-in-One Platform for Systematic Reviews & Meta-Analyses

BioClaritas automates every step of a systematic review — from PubMed search and title-abstract screening to full-text data extraction, meta-analysis, causal inference, DAG evaluation, and publication-ready scientific illustrations. Designed for researchers, clinicians, epidemiologists, and students, BioClaritas is a smarter alternative to Rayyan, Covidence, RevMan, DistillerSR, and EPPI-Reviewer.

Automated Screening & Study Selection

Screen thousands of studies in minutes. BioClaritas applies your inclusion and exclusion criteria to every title and abstract — accelerating screening while maintaining transparency and reproducibility. Supports PICO framework, boolean logic, and custom screening protocols.

Automated Data Extraction

Extract study characteristics, outcomes, effect sizes, confidence intervals, sample sizes, and methodological details automatically from full-text articles. BioClaritas reads full-text papers and populates extraction tables — eliminating hours of manual data entry. Works with PubMed Central full-text and uploaded documents.

Meta-Analysis & Statistical Synthesis

Perform meta-analyses directly within BioClaritas. Generate forest plots, funnel plots, and calculate pooled effect sizes with fixed-effect and random-effects models (DerSimonian-Laird, REML). Assess heterogeneity with I², Q-statistic, and tau². Conduct subgroup analyses and sensitivity analyses without needing RevMan, Stata, R metafor, or other statistical software. A complete meta-analysis assessment tool built into your review workflow.

PRISMA 2020 Compliance

BioClaritas automatically tracks your review workflow and generates PRISMA 2020-compliant flow diagrams. Every step — identification, screening, eligibility, inclusion — is documented with counts and reasons for exclusion, ensuring your systematic review meets Cochrane and journal submission standards.

Causal Relation Extraction & DAG Construction

Extract causal relationships (subject → mechanism → object) from the literature and build interactive Directed Acyclic Graphs (DAGs) for causal inference. Visualize complex biological and clinical relations, identify confounders and mediators, and generate publication-ready causal diagrams that supplement your systematic review findings.

Knowledge Graph Visualization

Explore extracted evidence as interactive knowledge graphs with hierarchical, circular, and concentric layouts. Identify key molecular players, hub genes, and central mechanisms using network metrics (betweenness centrality, PageRank). Cluster related relations automatically and generate narrative summaries of each cluster.

Scientific Illustrations & Graphical Abstracts

Create professional scientific illustrations, mechanism figures, and graphical abstracts. Generate publication-ready artwork for journal submissions without design experience. Perfect for creating visual summaries of your systematic review or meta-analysis findings. A powerful illustration tool integrated into your research workflow.

Risk of Bias & Quality Assessment

Assess study quality with built-in risk-of-bias tools supporting RoB 2 (revised Cochrane tool for randomized trials), ROBINS-I (non-randomized studies), Newcastle-Ottawa Scale, and custom quality assessment frameworks. BioClaritas can pre-fill assessments for reviewer validation.

Team Collaboration & Real-Time Sync

Invite collaborators to your systematic review project with role-based permissions (viewer, editor, admin). Work together in real-time with live syncing, shared screening decisions, dual-reviewer conflict resolution, and audit logging — essential for Cochrane-standard reviews.

Teaching Research Methodology & Study Design
