instruction: what is the daily minimum of output (ml)-chest tube #1 pleural right anterior;lower output of patient 006-167444 until 6 months ago?
response: SELECT MIN(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 = '006-167444')) AND intakeoutput.celllabel = 'output (ml)-chest tube #1 pleural right anterior;lower' AND intakeoutput.cellpath LIKE '%output%' AND DATETIME(intakeoutput.intakeoutputtime) <= DATETIME(CURRENT_TIME(), '-6 month') GROUP BY STRFTIME('%y-%m-%d', intakeoutput.intakeoutputtime)
