Dose-Proportionality Assessment Report

Upload concentration-time data with at least 3 dose levels. The engine computes per-subject Cmax, AUC0-last and AUC0-∞, fits the power model ln(PK) = ln(a) + β·ln(Dose) + ε for each endpoint, and tests the 90 % CI of β against the Smith et al. 2000 dose-range-dependent acceptance window. You receive a clean PDF and a Word draft structured along ICH M4 Module 5.3.1.2 — exploratory, not yet validated against reference software.

Exploratory — under validation. This module is not yet validated against reference software and is not intended for regulatory submission. Use for screening only.
Public beta — free while we gather feedback. Results are indicative, for research and internal QC, not a regulatory submission. Your dataset is processed in the EU and deleted within 1 hour.

▶ Accepted CSV format · click to expand

Required columns (case-insensitive, NONMEM aliases accepted):

  • TIME — time since dose. Aliases: time, t, tad, time_h, time_hr, tiempo, temps, zeit
  • DV — observed concentration. Aliases: dv, conc, concentration, y, obs, value, concentracion, konzentration, valeur

Optional columns: ID (required for per-subject NCA), AMT (dose), EVID (event ID), MDV (missing DV flag), RATE, DVID, CMT.

Header flexibility — punctuation, case, and parenthesised units are tolerated. Time (h), TIME_H, time-h and timeh all map to TIME. ES/FR/DE headers (tiempo, temps, zeit, etc.) are also accepted.

Minimum size: 4 distinct time points.

Example:

ID,TIME,DV,AMT,EVID
1,0,0,320,1
1,0.5,4.2,0,0
1,1,6.0,0,0
1,2,5.5,0,0
1,4,3.8,0,0
1,8,2.0,0,0
