instruction: what is the yearly average of output y (ml)-chest tube y - a #1 mid b #1 left lateral output of patient 007-2498 until 04/2104?
response: SELECT AVG(intakeoutput.cellvaluenumeric) FROM intakeoutput WHERE intakeoutput.patientunitstayid IN (SELECT patient.patientunitstayid FROM patient WHERE patient.patienthealthsystemstayid IN (SELECT patient.patienthealthsystemstayid FROM patient WHERE patient.uniquepid = '007-2498')) AND intakeoutput.celllabel = 'output y (ml)-chest tube y - a #1 mid b #1 left lateral' AND intakeoutput.cellpath LIKE '%output%' AND STRFTIME('%y-%m', intakeoutput.intakeoutputtime) <= '2104-04' GROUP BY STRFTIME('%y', intakeoutput.intakeoutputtime)
