Acute kidney injury in elderly patients receiving invasive mechanical ventilation: early versus late onset.
Observational study in European journal of medical research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundAcute kidney injury (AKI) is a severe complication in critical patients receiving invasive mechanical ventilation (MV). However, AKI which occurs in the first 48 h after MV (early AKI) and thus likely associated with the MV settings is probably different from AKI occurring following 48 h (late AKI). This study is aimed at exploring the incidence of early and late AKI in elderly patients receiving MV and identifying their different risk factors and outcomes.
methodsThis retrospective, observational, multicenter cohort study consecutively included 3271 elderly patients (≥ 75 years) receiving invasive MV at four medical centers of Chinese PLA General Hospital from 2008 to 2020. The diagnosis of AKI was made following the 2012 KDIGO criteria and categorized into early (≤ 48 h) or late (> 48 h-7 days) according to the time from MV.
resultsThere were totally 1292 cases enrolled for the final analysis. Among them, 376 patients (29.1%) developed early AKI versus 132 (10.2%) developed late AKI. The 28-day mortality rates of the non-AKI, early AKI, and late AKI patients were 14.4, 46.8, and 61.4%, respectively. After 90 days, mortality rates of three groups were 33.2, 60.6, and 72.7%, respectively. Risk factors for early AKI included PaO
conclusionsAKI mostly develops in the initial 48 h following MV, which is related to the health and MV settings; while AKI occurring following 48 h is not associated with MV settings. Therefore, a strategy for kidney protection in patients with MV should take these differences into consideration.
