Table 2

Suggested factors (range 1.0 – 0.1) for evaluation of the validity [V] of scientific papers and the assessment of type of expected effectiveness [TEE] (range 10.0 – 1.0).

Factor
Validity
Type of expected effectiveness (TEE) × 10 (prevention of ...)

1.00
Not impaired
Death
0.99 – 0.90
Almost not impaired with few deficiencies
life-threatening event
0.89 – 0.80

considerable impairment
0.79 – 0.70
impaired with deficiencies

0.69 – 0.60


0.59 – 0.50
clearly impaired with obvious deficiencies

0.49 – 0.40

Impairment
0.39 – 0.30
rather impaired with considerable deficiencies

0.29 – 0.20


0.19 – 0.10
seriously impaired
disturbed well-being

TEE describes the importance of a health-care service preventing either death, disability, or disturbance in well-being under day-to-day conditions. The International Classification of Functioning, Disability and Health (ICF) describes the foundations of this evaluation.
