Misclassification-adjusted prevalence
Apply sensitivity and specificity to an apparent prevalence estimate.

Use proportions from zero to one. Sensitivity plus specificity must exceed one. Accuracy estimates must apply to the population and measurement procedure.
The starting values are hypothetical. Results update as you edit. Use aggregate or synthetic inputs only.

How to interpret the output
Rogan–Gladen adjusted prevalence=(apparent prevalence+specificity−1)/(sensitivity+specificity−1). A result outside 0–1 signals incompatible inputs or estimation variability and is not silently clipped. This point calculation treats sensitivity and specificity as fixed and supplies no uncertainty interval.
