As described in the companion review by Schmidt and Factor in this issue, assessment of spectrum bias
depends on a comparison of patient populations.
Similarly, an analogous plot was used to identify spectrum bias.
A similar plot was used to examine the group of studies for possible spectrum bias.
in musculoskeletal medicine: how we can disagree and both be right?
With differences as large as this, the influence of spectrum bias on the results might need to be considered.
Spectrum bias in the evaluation of diagnostic tests: lessons from the rapid dipstick test for urinary tract infection.
3) quantified the effect of spectrum bias
, which arises when clinicians enroll very ill patients and compare their results with those from healthy controls.
The metaanalysis focused the appraisal of study quality on the potential for differential reference standard bias (10) and spectrum bias (11).
Thus, it can be speculated that because of spectrum bias, the diagnostic indexes derived in this metaanalysis will be slightly different from those that will be observed in real practice.

on the utility of magnetic resonance imaging and evoked potentials in the diagnosis of suspected multiple sclerosis.
