ToolTarget athletesAimNumber of parametersScore (points) and criteria

EROS-CLINICALSuspected of OTS (possible signs of imminent or incipient OTS)Diagnosis of OTS in suspected athletes, easy-to-perform and not time- or fund-consuming90–2 = excluded for OTS
3–5 = inconclusive
6–9 = diagnosis of OTS

EROS-SIMPLIFIEDSuspected of OTS when the diagnosis was not confirmed using the EROS-CLINICAL criteriaDiagnosis of OTS in suspected athletes when the diagnosis was not confirmed using the EROS-CLINICAL criteria130–3 = excluded for OTS
4–6 = inconclusive
7–8 = probable OTS
9–13 = diagnosis of OTS

EROS-COMPLETEPopulation-based screenings; athletes participating in research
Exception, suspected of OTS when the diagnosis was not confirmed using the EROS-SIMPLIFIED criteria
Diagnosis of OTS in large populations of athletes, irrespective of the risk or probability of OTS
Identification of risk factors, biomarkers, and tools for the prevention and diagnosis of OTS
Exception, individual diagnosis of OTS when the diagnosis was not confirmed using the EROS-SIMPLIFIED criteria
200–4 = excluded for OTS
5–10 = inconclusive
11–20 = diagnosis of OTS

EROS-RISKAt high risk for OTS (absence of clinical or biochemical signs)Prevention of OTS in high-risk athletes110–1 = low risk of OTS
2–4 = moderate risk of OTS
5–6 = high risk of OTS
7–11 = imminent risk of OTS

OTS = overtraining syndrome.
