Metric Options: CountsSelecting 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
Objective: To determine the relation between high arterial oxygen tension levels (Pao) and long-term mortality in patients with spontaneous intracerebral hemorrhage treated in the ICU. Design: National observational multicenter cohort study. Setting: Twenty-one ICUs in Finland. Patients: A total of 3,033 adult patients. Interventions: None. Measurements and Main Results: Patients were divided into high (> 150 mm Hg), intermediate (97.5-150 mm Hg), and low (< 97.5 mm Hg) Pao groups based on the lowest measured Pao/Fio ratio during the first 24 hours after ICU admission: 63% (n = 1,923) were in the low group, 29% (n = 892) were in the intermediate group, and 7% (n = 218) were in the high group; 80% were mechanically ventilated. The primary outcome was 6-month mortality, which occurred in 49% of patients and was significantly more frequent in the high Pao group than in the intermediate and low Pao groups (61% vs 52% and 46%, respectively, p < 0.001). In univariate analysis, patients in the high Pao group had a significantly increased risk of 6-month mortality compared with the low Pao group (odds ratio, 1.82; 95% CIs, 1.36-2.42; p < 0.001), but this statistically significant relation was lost after adjusting for markers of severity of illness in a logistic mixed-effects regression model (odds ratio, 1.10; 95% CI, 0.76-1.60; p = 0.598). Conclusions: No significant relation between Pao levels and long-term mortality was found. The clinical role of hyperoxemia in patients with intracerebral hemorrhage treated in the ICU remains controversial and warrants further studies.
