Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Objectives: Critical illness can cause severe cognitive impairments. The objective of this trial was to assess the effect of nonsedation versus sedation with a daily wake-up call during mechanical ventilation on cognitive function in adult survivors of critical illness. Design: Single-center substudy of the multicenter, randomized Non-sedation Versus Sedation With a Daily Wake-up Trial in Critically Ill Patients Receiving Mechanical Ventilation trial. Three months after ICU-discharge participants were tested for cognitive function by a neuropsychologist. Setting: Mixed 14-bed ICU in teaching hospital. Patients: A total of 205 critically ill, orally intubated, and mechanically ventilated adults. Interventions: Patients were randomized within the first 24 hours from intubation to either nonsedation with sufficient analgesia or light sedation with a daily wake-up call during mechanical ventilation. Measurements and Main Results: A total of 118 patients survived to follow-up and 89 participated (75%). The participating survivors in the two groups did not differ regarding baseline data or premorbid cognitive impairments. Sedated patients had received more sedatives, whereas doses of morphine and antipsychotics were equal. The primary outcome was that no significant difference was found in the number of patients with mild/moderate cognitive impairments (six nonsedated patients vs four sedated patients) or severe cognitive impairments (16 nonsedated patients vs 17 sedated patients; p = 0.71). Secondary outcomes were cognitive test scores, and no differences were found between the scores in nonsedated and sedated patients. Hypothetical worst case scenarios where all patients, who had not participated in follow-up assessment, were assumed to have severe cognitive impairments were analyzed, but still no difference between the groups was found. We found more patients with delirium in the sedated group (96% vs 69% of patients; p = 0.002) and increased duration of delirium in sedated patients (median 5 vs 1 d; p < 0.001). Delirium subtypes were equally distributed between the groups, with hypoactive delirium most frequent (61%), followed by mixed delirium (39%). Conclusions: Nonsedation did not affect cognitive function 3 months after ICU-discharge.
