instruction: is systemicmean of patient 002-13643 second measured on the first intensive care unit visit greater than the first value measured on the first intensive care unit visit?
response: SELECT (SELECT vitalperiodic.systemicmean FROM vitalperiodic WHERE vitalperiodic.patientunitstayid IN (SELECT patient.patientunitstayid FROM patient WHERE patient.patienthealthsystemstayid IN (SELECT patient.patienthealthsystemstayid FROM patient WHERE patient.uniquepid = '002-13643') AND NOT patient.unitdischargetime IS NULL ORDER BY patient.unitadmittime LIMIT 1) AND NOT vitalperiodic.systemicmean IS NULL ORDER BY vitalperiodic.observationtime LIMIT 1 OFFSET 1) > (SELECT vitalperiodic.systemicmean FROM vitalperiodic WHERE vitalperiodic.patientunitstayid IN (SELECT patient.patientunitstayid FROM patient WHERE patient.patienthealthsystemstayid IN (SELECT patient.patienthealthsystemstayid FROM patient WHERE patient.uniquepid = '002-13643') AND NOT patient.unitdischargetime IS NULL ORDER BY patient.unitadmittime LIMIT 1) AND NOT vitalperiodic.systemicmean IS NULL ORDER BY vitalperiodic.observationtime LIMIT 1)
