Areas under the SROC curve with 95% confidence intervals (error bars) per modality for subgroups. Prevalence refers to the prevalence of disease in the studied population. Fully blinded is defined as reading the images without any knowledge about the patient. Clinical info indicates that readers were aware of clinical information about the patients, but had no knowledge about results from other imaging studies. In some subgroups columns are missing for one or more modalities, because no or only one study was available for that subgroup and thus the subgroup analysis could not be performed
