Ainamo Gingival Bleeding Index Calculator

Known-positive percentage for actual Ainamoand Baygingival bleeding sites with distinct actual site IDs and unknown evidence retained; examination/protocol qualification external. Not universality, whole-mouth imputation or disease diagnosis.

Description

A bleeding index describes positive observations among assessed sites.

A bleeding index describes positive observations among assessed sites.^[1]

Unassessed sites must remain outside the known-observation denominator. Use this tool to calculate the stated observation or conditional model from supplied measurements.

When to use Ainamo Gingival Bleeding Index Calculator

Use this tool to calculate the stated observation or conditional model from supplied measurements. Establish the qualified examination or measurement context, matching instrument/protocol edition, site order and units.

How to use Ainamo Gingival Bleeding Index Calculator and understand its results

Establish the qualified examination or measurement context, matching instrument/protocol edition, site order and units.
Enter callerExaminedSiteIds, independentlyObservedBleedingFlags, siteEvidenceKnownFlags, using the field meanings and rules below, then run the tool.
Read result.observedKnownPositivePercent, result.knownObservationCount, result.unknownObservationIds. Interpret each field using the units, signs and evidence rules below.
If input validation fails, correct the reported field and run again. Before applying a successful result, check the stated reference scope, units, assumptions and any retained unknown evidence.

Input field	Meaning	Value type	Requirement
callerExaminedSiteIds	Caller examined site ids	list of string	Required
independentlyObservedBleedingFlags	Independently observed bleeding flags; binary 0/1 in the order documented below	list of number	Required
siteEvidenceKnownFlags	Site evidence known flags; 1 means known and 0 means unknown; keep the same item order	list of number	Required

Supply nonempty unique nonblank site IDs with aligned binary finding and known flags. Require at least one known observation. Count findings whose finding=1 and known=1, divide by known count and scale by 100. Return the known count and unknown IDs in caller order; unknown positive placeholders do not enter the numerator. No sites or clinical findings are inferred.

knownPositivePercent=100×Σ(finding_i×known_i)/Σknown_i; unknownIds={id_i:known_i=0}

Apply the field units and exact ordering, boundary and evidence rules above.

Output field	Meaning	Value type
result	Structured result containing the calculation or selected reference fields below	object
result.observedKnownPositivePercent	Observed Known Positive Percent; use the units, sign convention and calculation stated above	number
result.knownObservationCount	Known Observation Count; use the units, sign convention and calculation stated above	number
result.unknownObservationIds	Unknown Observation Ids; use the units, sign convention and calculation stated above	list of string

Limitations and assumptions

Unassessed sites must remain outside the known-observation denominator. Results depend on the independently established measurement basis and the exact model assumptions above.

Every listed input requires an explicit value. Unexpected fields, incorrect value types, nonfinite numbers and sparse numeric arrays fail validation; tool-specific bounds and alignment rules apply as described above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful calculation that reports a false comparison or retains unknown evidence.
