The association between cortisol dynamics and the course of aneurysmal subarachnoid hemorrhage.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
contextOne of aneurysmal subarachnoid hemorrhage complication is delayed ischemic neurological deficits (DIND). It is postulated that cortisol dynamics might be associated with the severity of this complication.
aimsThe goal of the study is to investigate whether the peak of morning serum cortisol levels are associated with the severity of its complication during the course of the disease. SETTINGS AND
designThis is a prospective cohort study conducted from January 2009 to June 2011, at our institution. MATERIALS AND
methodsThe study follows a consecutive cohort of patients for 14 days after the aneurysmal subarachnoid hemorrhage. Serum cortisols, cortisol binding globulin, adenocorticotrophic hormone (ACTH) were measured pre operatively and then on post operative days (POD) 2, 4, 7, and 10. Blood was drawn to coincide with peak cortisol levels between 08.00-09.00 hours. Neurological examinations were conducted at least twice daily and patient outcome were graded according to modified Ranklin Scale. DIND was defined by a decrease in the Glasgow Coma Scale of two or more points compared to the status on POD 1. STATISTICAL ANALYSIS: All the results were analyzed using statistical software, Statistical Package for Social Sciences (SPSS v61; SPSS, Inc., Chicago, IL). Logistic regression analysis was used to compare the relationship between the variables.
resultsThirty six consecutive patients are collected, but only 28 patients (12 M and 16 F) were eligible for the cohort analysis. Average patient age is 50.75 years old (50.75±12.27), and more than 50% (15/28) arrived with World Federation of Neurologic Surgeons grade 3 or better. Elevated total cortisol levels of more than 24 mg/dl on day 2, 4, and 10 were associated with DIND, and the most significant being on day 4 (P=0.011). These patients also had a higher grade on the modified Ranklin scale of disability.
conclusionsThis study shows that the elevated levels of morning total cortisol in the serum are associated with the onset of DIND during the disease course, and it's also associated with bad outcomes.
