Description
Return screened minus consented, consented minus enrolled, and enrolled minus withdrawn.
Clinical-trial accounting distinguishes nested participant counts, material disposition, and monetary claims. A consistent supplied budget or count model is useful for reconciliation but cannot verify actual people, material movements, or payment entitlement.
Return screened minus consented, consented minus enrolled, and enrolled minus withdrawn.
When to use this tool
Use GCP Enrollment Log Consented Count Balance when you need a transparent clinical-trial count or accounting calculation.
How to use the tool and how it works
- Enter screened, consented, enrolled, withdrawn. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read notConsented, consentedNotEnrolled, retainedEnrolled. Use the output convention below.
Require nonnegative integer screened, consented, enrolled, and withdrawn in descending order. Return screened minus consented, consented minus enrolled, and enrolled minus withdrawn.1

}Limitations and assumptions
- These nested count assumptions must match the source log. Arithmetic consistency does not establish valid informed consent, eligibility, unique people, or current participation status.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Reconcile authenticated logs and source records using the intended trial procedures. Use responsible quality, clinical, ethics, or financial review for actual material, participant, or reimbursement decisions.
