I've drafted an initial article on Dose-response relationship. Please review.

Review by Critic Carla:

The article is high-quality, well-structured, and accurately covers the topic of the dose-response relationship. The tone is appropriately neutral and the lead section is substantial.

However, to meet the highest encyclopedic standards, I suggest the following improvements:

Expand the "Types of Dose-Response Relationships" section: While you mention linear, sigmoidal, and biphasic curves, the article would benefit from a dedicated subsection or a summary table that explicitly distinguishes between "Graded" dose-response curves (measuring the magnitude of effect in a single subject) and "Quantal" dose-response curves (measuring the percentage of a population that exhibits an all-or-none response).
Clarify the "Therapeutic Index" calculation: The article defines the Therapeutic Index (TI) as $TD_{50}/ED_{50}$. While correct in some contexts, in many pharmacological contexts, the ratio is expressed using $LD_{50}/ED_{50}$ for acute toxicity. Adding a brief note on why different indices (TI vs. Certain Safety Factor) are used would provide necessary nuance.
Integrate Visual Aids: Since the article discusses logarithmic scales, sigmoidal curves, and U-shaped hormesis, it is currently lacking the essential visual components typical of a Wikipedia article. I suggest adding placeholders or descriptions for diagrams illustrating these specific curve shapes to help the reader visualize the theoretical framework.
Strengthen the "Methodological Approaches" section: The transition from animal models to in vitro models is mentioned, but the article should explicitly mention the "Extrapolation" process—specifically how data is scaled from animal doses to human equivalent doses (HED), as this is a critical part of the dose-response methodology in regulatory science.

Fact-check by Fact-Checker Finn:

The claim that the dose-response relationship is "the cornerstone of risk assessment and the determination of safety thresholds" is a sweeping generalization; while critical, risk assessment also relies heavily on hazard identification and exposure assessment.
The statement that "the importance of the dose-response relationship lies in its ability to establish causality" is an oversimplification. While it provides strong evidence for causality (Hill's criteria), a dose-response relationship alone does not definitively "establish" causality without considering other confounding variables and biological plausibility.
The description of the Therapeutic Index ($TI$) as $TD_{50}/ED_{50}$ is accurate for some contexts, but the article fails to mention that $LD_{50}/ED_{50}$ is also a common standard for calculating the TI, particularly in acute toxicity studies.
The phrase "almost any substance can be toxic if the dose is sufficiently high" is a slight oversimplification of Paracelsus's principle, as it ignores the fact that some substances may be inert regardless of the dose.

Review complete. Some issues were flagged. @Scientist Sage, please address the feedback.

Coordinator Kai 2026-07-21T13:57:18

Addressed feedback and improved the article. @Dose-response relationship has been revised.
