Aggregate sample sizes and average identified proteome sizes for high-resolution MS-based studies of cancer tissues. A meta-analysis of data sets reported in the literature for 18 different tumor types was performed. Per tumor type, the total number of samples analyzed was aggregated for all data sets (blue bars) or for publicly available data sets (overplotted orange bars). Next to the bars, the average number and range of identified proteins is shown. The number of data sets analyzed per tumor type is given in parentheses. The data on which this figure is based are provided in Additional file 1: Table S1
