Establishing outcome MHQIs for these may be limited to prevalence indicators of events such as self harm, harm to others, and control procedures.
They are used as indicators of events along the toxicological pathway, including toxicokinetics (exposure, internal dose, and biologically effective dose) and toxicodynamics (early biological effect, altered structure and function, and clinical disease) (National Research Council Committee on Biological Markers 1987).
Multivariate analyses (Cox proportional hazards model) of the factors associated with event-free survival on univariate analyses identified preoperative BTR <5, ALT ≥42 IU/l, and AT VO2 <11.5 ml/min/kg as independent prognostic indicators of event-free survival (Table 3).
In patients with hepatocellular carcinoma and hepatic dysfunction who underwent liver resection, preoperative exercise capacity and branched-chain amino acid/tyrosine ratio were identified as independent prognostic indicators of event-free survival and maintenance of Child-Pugh class.
Univariate and multivariate analyses were performed to evaluate associations between 35 clinical factors and outcomes, and identify independent prognostic indicators of event-free survival and maintenance of Child-Pugh class.
In conclusion, preoperative exercise capacity and BTR were identified as independent prognostic indicators of event-free survival and maintenance of Child-Pugh class in HCC patients with chronic liver injury undergoing hepatectomy.
Multivariate analyses identified preoperative branched-chain amino acid/tyrosine ratio (BTR) <5, alanine aminotransferase level ≥42 IU/l, and AT VO2 <11.5 ml/min/kg as independent prognostic indicators of event-free survival.
In multivariable analysis, the most powerful independent prognostic indicator of events was group IV (hazard ratio 12.6, 95% confidence interval 2.2 to 74.2, p = 0.005).
Charles Musser, a film historian, writes that "the front page of the New York Journal was an excellent indicator of events considered worthy of the Kinetograph Department's attention throughout 1901-1902".
where is the inverse of function, is the indicator of event.
In this data set, pid is the subject identifier, tstart is time of previous event or study start, tstop is time of event or censoring, status is an indicator of event, and grp is the covariate for group membership.
