10 . The information processing system according to claim 9 , wherein
the selection unit is configured to select reference medical information such that in a case where a command to switch the selection condition is accepted, the selection unit selects reference medical information according to a second selection condition which is included in the plurality of selection conditions extracted for the specified medical information and which is different from the one of the selection conditions, and the change unit is configured to change an appearance of the reference medical information selected according to the second selection condition to an appearance different from an appearance of medical information other than the reference medical information, and return the appearance of the reference medical information selected according to the one of the selection conditions to the previous appearance employed before the appearance is changed.
11 . The information processing system according to claim 4 , wherein the selection condition further includes a condition for specifying a type of the reference medical information.
12 . The information processing system according to claim 1 , wherein the selection unit is configured to select the reference medical information such that association information associated to the specified medical information is acquired from a second storage unit in which association information indicating the association of the specified medical information is stored in association with the specified medical information, and the reference medical information is selected based on the acquired association information.
13 . The information processing system according to claim 12 , wherein the selection unit is configured to select reference medical information such that in a case where a plurality of pieces of association information are associated to one piece of specified medical information, based on each of the plurality of pieces of association information.
14 . The information processing system according to claim 13 , wherein the change unit is configured to change appearances of the plurality of pieces of reference medical information selected based on the respective pieces of association information to appearances different from each other.
15 . The information processing system according to claim 4 , wherein the selection unit is configured to select reference medical information such that association information associated to the specified medical information is acquired from a second storage unit in which the specified medical information is stored in association with the association information indicating the association of the specified medical information, and associated medical information associated with the specified medical information is selected based on the acquired association information and then, based on the selection condition, the reference medical information is selected from the associated medical information.
16 . The information processing system according to claim 1 , wherein the change unit is configured to highlight the appearance of the reference medical information.
17 . The information processing system according to claim 1 , wherein changing the appearance includes one or more of:
changing a display frame of the reference medical information so as to be displayed in a line that thicker than a line used to display the medical information other than the reference medical information; changing a line type of the display frame of the reference medical information so as to be different from a line type used by the medical information other than the reference medical information; changing a color of the display frame of the reference medical information so as to be different from a color used by the medical information other than the reference medical information; changing a background color of the reference medical information so as to be different from a background color used by the medical information other than the reference medical information; and c
