Built for Epidemiologists, Clinicians & Researchers
You understand the statistics.
We handle the R.
JOANResearchOS runs epidemic curves, attack rate tables, survival analysis, and 16 other statistical tests — just by describing your research question in plain language.
AI generates the R code. R computes every p-value, confidence interval, and effect size. You get a PDF report ready for DOH, WHO, or your ethics board.

Epidemiology-specific features
Built for outbreak investigation and surveillance
The EpiR Handbook is used by 850,000 epidemiologists worldwide — because R is powerful but hard. JOANResearchOS makes every chapter of the handbook accessible without writing a single line of code.
📈
Epidemic Curves
EpiR Handbook Ch. 32
Auto-generates an epicurve from your case line list. Automatically selects daily, weekly, or monthly intervals based on outbreak duration. Identifies peak period and case counts.
Date of onsetAuto-interval selectionPeak detection
⚔️
Attack Rate Tables
EpiR Handbook Ch. 16
Standard 2x2 outbreak table comparing exposed vs unexposed groups. Calculates attack rates per group, Risk Ratio, Odds Ratio, Attributable Risk, and Population Attributable Risk.
Risk RatioOdds RatioAttributable Risk
🔺
Age-Sex Pyramids
EpiR Handbook Ch. 33
Demographic breakdown of cases by age group and sex. Auto-bins numeric ages into standard epi groups (0-4, 5-9... 75+). Calculates median and mean age by sex.
Standard age groupsSex breakdownProportions
⏱️
Survival Analysis
EpiR Handbook Ch. 27
Kaplan-Meier curves, case fatality rate, and median survival time from symptom onset to outcome. Stratified analysis by severity, vaccination status, or comorbidities.
CFRKaplan-MeierCox regression
📉
Moving Averages
EpiR Handbook Ch. 22
7-day and 14-day rolling averages to smooth surveillance noise. Detects peak timing, trend direction (increasing/decreasing), and weekly totals for situational reports.

14 More Statistical Tests
All automatically selected
Chi-square, Fisher's Exact, logistic regression, Mann-Whitney, Kruskal-Wallis, t-tests, ANOVA, correlations, and more — all triggered by describing your research question.

From case line list to outbreak report in minutes
No R installation. No coding. No waiting for a statistician.
01
Upload your Excel case line list
Drag and drop your .xlsx file. The system reads column names, detects date columns, identifies variable types, and flags missing values automatically.
02
Describe your investigation question
Type in plain language: "What is the epidemic curve by symptom onset date?" or "What is the attack rate among vaccinated vs unvaccinated cases?" No special syntax needed.
03
AI selects the correct epi test
JOANResearchOS reads your data profile and question, selects the appropriate analysis (epidemic curve, attack rate table, survival analysis, etc.), and generates the R code.
04
R executes and computes every value
The R statistical engine runs the analysis. Every attack rate, risk ratio, p-value, and survival estimate is computed by R — not estimated or fabricated by AI.
05
Download your PDF outbreak report
Professional report with your research question, analysis plan, full statistical output, AI interpretation, and the complete R script for reproducibility and audit trail.
Results you can publish, present, and defend
Every design decision was made with one goal: statistical output that meets academic and public health reporting standards.
🔬
R is the only calculator
AI never estimates or computes statistical values. Every attack rate, risk ratio, p-value, confidence interval, and effect size comes exclusively from R — the gold standard used by WHO, CDC, and IATF.
📋
Full audit trail
Every analysis includes the complete R script and verbatim R console output. Any biostatistician can re-run it independently and get identical results. Perfect for DOH and ethics board submissions.
🏥
DOH and WHO aligned
Output format follows standard epidemiological reporting conventions. Attack rate tables, epicurves, and survival analysis are structured to match what surveillance reports and outbreak investigations require.

Frequently asked questions
Can I trust the results for DOH or WHO reports?
Yes. All calculations are performed exclusively by R — the same statistical engine used by WHO, CDC, and the Philippine DOH. AI generates code and interprets output only. Every analysis includes the R script and raw output for full reproducibility and audit trail.
Does it work with my standard case line list format?
Yes. Upload any .xlsx file with your case data. The system automatically detects date columns, identifies variable types (categorical, numeric, date), and handles common issues like missing values and merged cells.
Is the free plan really free?
Yes. No credit card required. You get 5 analyses per month with all 19 statistical tests including all 5 epidemiology-specific tests — enough to run a full outbreak investigation.
How do I pay for Pro or Institution?
Contact us via the button above and we will send you a GCash or bank transfer payment link. Access is activated within 24 hours of payment confirmation.
Can multiple epidemiologists from my team use it?
Yes. The Institution plan supports up to 20 team members with a shared admin dashboard. Each member has their own account and analysis history.
