Description

midas quadas displays a QUADAS-2 (Quality Assessment of Diagnostic
Accuracy Studies) summary chart. QUADAS-2 assesses methodological quality
of primary diagnostic accuracy studies across four domains: patient
selection, index test, reference standard, and flow and timing.

Each domain is assessed for risk of bias and (for the first three domains)
applicability concerns. The assessment variables should be coded as
1 = low risk/concern, 2 = high risk/concern, 3 = unclear.

Options

id(varname) study identifier variable.

robvars(varlist) variables encoding risk-of-bias judgements,
one per QUADAS-2 domain.

acvars(varlist) variables encoding applicability concern
judgements.

plot(string) plot type: bar for a bar chart of
proportions, or sum for a study-level summary chart.

color uses color coding (green/red/yellow for low/high/unclear).

saving(filename) saves the graph to filename.

Example

. midas quadas, id(study) robvars(rob1 rob2 rob3 rob4) acvars(ac1 ac2 ac3) plot(bar)
