Causal consulting for pharma

Better study interpretation for pharmacological evidence that comes with real-world constraints.

Causality Graphs works with pharma, clinical research, and biostatistics teams to map assumptions, review confounding structure, and support evidence decisions using directed acyclic graphs and dynamic causal models.

Single-arm studiesPartial blindingLongitudinal responseEvidence strategy

Assumption mapping

Make confounding, mediation, and selection logic explicit before interpretation hardens.

Dynamic modeling

Bring time, feedback, and evolving treatment response into the causal picture.

Decision support

Support evidence strategy when controls are limited, partial, or operationally imperfect.

Built for technical stakeholders

Built for clinical teams, biostatistics groups, translational medicine, and evidence strategy leaders.

The approach is designed for research environments where methodological rigor, internal alignment, and practical decision-making all have to coexist.

What we do

Study interpretation, assumption mapping, and evidence strategy for non-ideal designs.

Causal study design support

Frame the causal question, clarify the estimand, and make design tradeoffs visible before analysis choices become default assumptions.

DAG review and modeling

Build and review graph-based representations of exposure, outcome, mediation, and confounding pathways to support defensible interpretation.

Dynamic causal analysis

Model systems that evolve through time when treatment response, adaptation, feedback, and pathway timing cannot be ignored.

Evidence strategy guidance

Translate causal reasoning into practical recommendations for study interpretation, internal alignment, and next-step evidence decisions.

Why it matters

When trial conditions are imperfect, decision risk sits in the structure as much as the numbers.

Many pharmacological studies operate with limited controls, partial blinding, evolving treatment pathways, or observational contamination.

Standard summaries can look convincing while still hiding confounding, collider bias, selection effects, or pathway ambiguity.

Explicit causal structure makes tradeoffs discussable, assumptions inspectable, and interpretation more defensible across teams.

Techniques preview

Methods chosen to answer causal questions, not to decorate an analysis plan.

Directed Acyclic Graphs

Map assumptions, identify adjustment sets, and make hidden structure legible.

Useful when teams need a shared causal language before modeling begins.

Dynamic causal models

Represent how biological and treatment systems evolve rather than treating time as a nuisance.

Useful for longitudinal response, feedback, adaptation, and mechanistic interpretation.

Counterfactual reasoning

Anchor interpretation in explicit what-if contrasts instead of loose correlational claims.

Useful when decision-makers need clarity on treatment effect questions under constraints.

Sensitivity analysis

Stress-test conclusions against unmeasured bias, structural uncertainty, and model dependence.

Useful when evidence quality is limited but choices still need to be made.

Selected work

Representative consulting situations where explicit causal reasoning changed the recommendation.

Single-arm oncology signal review

Problem -> method -> impact

Challenge: A promising response pattern was difficult to interpret without a concurrent control.

Method: DAG refinement plus explicit counterfactual framing around likely confounding and selection processes.

Outcome: The study team gained a clearer interpretation boundary and a more credible next-evidence strategy.

Longitudinal treatment response mapping

Problem -> method -> impact

Challenge: Dose changes, dropouts, and symptom dynamics blurred the treatment story over time.

Method: Dynamic causal modeling to separate temporal structure, pathway timing, and evolving response states.

Outcome: The resulting model supported better reasoning about progression, timing, and endpoint relevance.

Partial-blinding evidence interpretation

Problem -> method -> impact

Challenge: Operational realities introduced expectation effects and outcome interpretation risk.

Method: Structured causal assumptions, mediation review, and sensitivity framing for interpretation robustness.

Outcome: Leadership received a cleaner account of what could be claimed and what required caution.

Philosophy

The work is collaborative, assumption-aware, and designed to hold up across teams.

Make assumptions explicit before they become invisible defaults.

Separate structural signal from statistical convenience.

Use causal thinking to improve decisions, not just analysis complexity.
