Adequate daily blood glucose control
Represented as median hours spent each day within the target range per patient
1 article [21]

Correlation between within-run mean BGL and within-run mean coefficient of variance for hourly insulin rate
To illustrate whether hyperglycaemia after attaining target is correlated with variability in infusion rate
1 article [9]

Correlation between within-run mean BGL and within-run mean hourly insulin rate
To illustrate whether the protocol performed equally well independent of insulin resistance
1 article [9]

Distribution of the individual patient BGL mean in a predefined time interval
Represented in box plot
1 article [11]

Number of patients with well and poor BGL control
Represented as percentage of patients and defined as:
• well controlled patient: <130a BGL for more than half of the measured time; or
• poor controlled patient: <130 BGL for less than or equal to half of the measured time.
1 article [31]

Odds ratio of achieving certain BGL
Per additional Intensive Care day and some drugs
1 article [50]

Number of patients having defined mean BGL
Represented as percentage of patients with mean BGL ≥ 200 for each day after surgery
1 article [22]

Probability density function for BGL measurements
Represented as a curve for comparison with other protocols
1 article [35]

Proportion of patient-day with mean BGL<200 and ≥ 200 and IIT at least in part of the day

1 article [22]

Number of report on necessary departure from protocol, clinical intervention or adverse events

1 article [35]

Time from admission to first BGL
Represented as mean of time [15]
1 articles [15]

Variability after achieving target
Represented as within-run mean (IIT episode) ± standard deviation and mean of within-run coefficient variance ± standard deviation (%)
1 article [9]

aUnit of all BGL thresholds is mg/dl. BGL, blood glucose level; IIT, intensive insulin therapy.
