Extracted output data stored in Matlab data structure. Contains [1×30] structure ‘vtrial’, which contains [1×2] character ‘patient’ (01 to 30, gives patientID) and [1×2] structure ‘dev’ ([1] for TOMOFIX, [2] for TOKA). The structure ‘dev’ contains [1×7] character ‘name’ and [1×3] structure ‘sc’ (screw configurations 1 to 3). The structure ‘sc’ contains [1×2] structure ‘hs’ (healing stages 2, 3, 4). The structure ‘hs’ contains [0×0] double-precision array ‘lstep’ (loadsteps 1 to 15).
