| Row 1: | Shows the value of REFID=STM, This REFID refers to the trial set with a SETCD of 'SetSTM', as defined in the trial set dataset, tx.xpt. LEVEL=1 and LVLDESC='TRIAL SET' indicates this identifier relates to the entire trial set. |
| Row Rows 1, 2, 8, 12, 16: | Shows that the trial set, SetSTM, is the parent of set codes SetA, SetF, SetG, and SetR. |
| Row 2: | Shows the value of REFID=A, This REFID refers to the trial set with a SETCD of 'SetA', as defined in the trial set dataset, tx.xpt. LEVEL=2 and LVLDESC='TRIAL SET' indicates this identifier relates to the entire trial set. |
| Rows 3-7: | Show the values of five observational units 1_1 through 1_5 that are within the parent experimental unit, REFID=A |
| Row 8: | Shows the value of REFID=F, This REFID refers to the trial set with a SETCD of 'SetF', as defined in the trial set dataset, tx.xpt. LEVEL=2 and LVLDESC='TRIAL SET' indicates this identifier relates to the entire trial set. |
| Rows 9-11: | Show the values of three observational units 6_1 through 6_3 that are within the parent experimental unit, REFID=F |
| Row 12: | Shows the value of REFID=G, This REFID refers to the trial set with a SETCD of 'SetG', as defined in the trial set dataset, tx.xpt. LEVEL=2 and LVLDESC='TRIAL SET' indicates this identifier relates to the entire trial set. |
| Rows 13-15: | Show the values of three observational units 7_1 through 7_3 that are within the parent experimental unit, REFID=G |
| Row 16: | Shows the value of REFID=R. This REFID refers to the trial set with a SETCD of 'SetG', as defined in the trial set dataset, tx.xpt. LEVEL=2 and LVLDESC='TRIAL SET' indicates this identifier relates to the entire trial set. |
