✦ New Feature
Line List Builder
Transform raw KoboToolbox exports, PIDSR data, Google Forms, and hospital EMR files into clean, de-identified WHO-standard line lists — directly in your browser.
PHI never leaves your device. All cleaning happens client-side. Only the de-identified output uploads to JOANResearchOS.
📋
KoboToolbox / ODK
Auto-strips _uuid, _submission_time, GPS columns. Detects source on upload.
🏥
PIDSR Export
Maps PIDSR columns to WHO line list standard. Philippine-specific field recognition.
📝
Google Forms
Removes Timestamp, Email Address. Renames Q-prefixed columns automatically.
💊
Hospital EMR / HEIS
Strips PatientID, MRN, encounter metadata. Keeps clinical analysis fields.
Epidemiology-specific features
Built for outbreak investigation and surveillance
The EpiR Handbook is used by 850,000 epidemiologists worldwide. JOANResearchOS makes every chapter accessible without writing a single line of code.
📈
Epidemic Curves
EpiR Ch. 32
Auto-generates epicurves from case line lists. Selects daily, weekly, or monthly intervals. Identifies peak period and case counts.
Date of onsetAuto-intervalPeak detection
⚔️
Attack Rate Tables
EpiR Ch. 16
Standard 2×2 outbreak tables. Calculates attack rates, Risk Ratio, Odds Ratio, Attributable Risk, and Population Attributable Risk.
Risk RatioOdds RatioAttributable Risk
🔺
Age-Sex Pyramids
EpiR Ch. 33
Demographic breakdown of cases. Auto-bins numeric ages into standard epi groups (0–4, 5–9... 75+). Median and mean age by sex.
Standard age groupsSex breakdownProportions
⏱️
Survival Analysis
EpiR Ch. 27
Kaplan-Meier curves, CFR, and median survival time from symptom onset to outcome. Stratified by vaccination, severity, or comorbidities.

📉
Moving Averages
EpiR Ch. 22
7-day rolling averages to smooth surveillance noise. Detects peak timing, trend direction, and weekly totals for situational reports.

From case line list to outbreak report
No R installation. No coding. No waiting for a statistician.
01
Clean your raw data (optional)
NEWUse the Line List Builder to clean KoboToolbox, PIDSR, or Google Forms exports. PHI detection, date standardization, and de-identification — all in your browser.
02
Upload your Excel case line list
Drag and drop your .xlsx file. AI detects column types, flags missing values, and runs pre-flight assumption checks before you spend an analysis credit.
03
Describe your investigation question
"What is the epidemic curve by symptom onset?" or "What is the attack rate among vaccinated vs unvaccinated cases?" Plain language — no syntax required.
04
AI selects the test and writes R code
JOANResearchOS selects the appropriate test, generates the R script, and shows you a pre-flight assumption check before executing.
05
R computes every value
Every attack rate, risk ratio, p-value, and confidence interval is computed by R — not estimated or fabricated by AI. Full audit trail included.
06
Download your DOH-ready PDF report
Professional report with your analysis plan, full R output, AI interpretation, and the complete R script for reproducibility. Ready for DOH, WHO, or ethics boards.
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 p-value, confidence interval, risk ratio, and effect size comes exclusively from R — the gold standard used by WHO, CDC, and Philippine DOH.
📋
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 analyses match what PIDSR, WHO surveillance reports, and outbreak investigations require.
