Impact of Early versus Delayed Vasopressin Initiation on 28-Day Mortality in Older Adults with Septic Shock.

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
Background: The optimal timing for initiating adjunctive vasopressin in septic shock remains controversial, with limited evidence specific to older adults who may have altered physiological responses. This study aimed to investigate the association between the timing of vasopressin initiation and 28-day mortality in older adults with septic shock. Methods: In this retrospective observational cohort study, we enrolled 197 older adults (≥65 years) with septic shock who received vasopressin within 72 hours of norepinephrine initiation. Patients were categorized into an early group (vasopressin within 6 hours of norepinephrine; n=119) and a delayed group (vasopressin between 6-72 hours; n=78). The primary outcome was 28-day all-cause mortality, analyzed using multivariable Cox regression adjusting for potential confounders. Results: The 28-day mortality was significantly lower in the early vasopressin group compared to the delayed group (36.1% vs. 57.7%, Conclusion: In older adults with septic shock, early initiation of vasopressin within six hours of norepinephrine commencement was independently associated with significantly lower 28-day mortality and improved hemodynamic and organ function outcomes.
