Flows of patients due to refined receptor diagnosis

Flow-label	Flow-category	IHC category		IHC & GE & CO category
(a)	Confirmed +	Definite +	→	Definite +
(b)	Confirmed −	Definite −	→	Definite −
(c)	Allocated +	Inconclusive	→	Definite +
(d)	Allocated −	Inconclusive	→	Definite −
(e)	Corrected to −	Definite +	→	Definite −
(f)	Corrected to +	Definite −	→	Definite +
(g)	Rejected +	Definite +	→	Inconclusive
(h)	Rejected −	Definite −	→	Inconclusive
(i)	Undetermined	Inconclusive	→	Inconclusive

Labels (a–i) are used in text and figures to reference specific flows. Each flow represents the change in category (definite −, definite +, inconclusive) due to enriched information
