Prevalence in general population (GP): rare [~0,75% | 1:1 | weight: 1,00]

Most likely diagnostic options for Auspitz signs - the appareance of punctacte bleeding spots when scales are scraped off {see video} (ranked by 'weight' for the general population):


psoriasis [30% | 1:40 | weight: 0,95]
• actinic keratosis [?% | 1:7 | weight: ?]
• Darier's disease [?% | 1:50K | weight: ?]



[1st figure = prevalence hand sign in condition | 2nd
figure = prevalence condition in GP | 3rd figure =
estimated hand sign weight for condition relative
to GP (>0,5 = present in majority of GP cases)]

[In every 100 Auspitz sign cases in the general population (GP) you can expect to find about 95 psoriasis cases, etc.]
