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: Critically ill immunocompromised patients are particularly susceptible to acute kidney injury (AKI) due to various underlying mechanisms. Although invasive mechanical ventilation has been associated with an increased risk of AKI, its specific impact on immunocompromised patients with acute respiratory failure has not been explored. This study aims to describe the prevalence of AKI in this patient population and evaluate the potential risk associated with invasive mechanical ventilation, using causal inference models adjusted for the likelihood of requiring ventilation. Results: We conducted a post-hoc analysis of 734 immunocompromised patients from the HIGH clinical trial. Of these, 302 (41%) required invasive mechanical ventilation, and 542 (74%) developed AKI. Notably, AKI frequently occurred before the initiation of invasive mechanical ventilation, with the median day of peak KDIGO stage being 2 days (IQR 1-4 days), compared to 3 days (IQR 2-4 days) for initiation of mechanical ventilation. While univariate analysis showed a significant association between invasive mechanical ventilation and AKI (OR = 1.08, 95% CI = 1.02-1.16, p = 0.014), this association was not significant in the multivariate model (OR = 1.05, 95% CI = 0.98-1.13, p = 0.185). Similar findings were observed after adjusting for the risk of invasive mechanical ventilation using overlap weighting and in a competing risk model. Among patients who received mechanical ventilation, 59 (19%) developed AKI after initiation of mechanical ventilation. Conclusion: Immunocompromised patients with acute respiratory failure face a significant risk of developing AKI, driven by a combination of factors such as their underlying conditions and disease severity. In contrast, the direct impact of invasive mechanical ventilation appears to be limited, suggesting that mechanical ventilation may not be a primary driver of AKI in this vulnerable patient population.
