Acute kidney injury in critically ill COVID-19 patients in a tertiary hospital: short and long-term kidney and patient outcomes.
Article in Jornal brasileiro de nefrologia. 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
introductionAcute kidney injury (AKI) in the setting of COVID-19 is associated with worse clinical and renal outcomes, with limited long-term data.
aimTo evaluate critically ill COVID-19 patients with AKI that required nephrologist consultation (NC-AKI) in a tertiary hospital.
methodsProspective single-center cohort of critically ill COVID-19 adult patients with NC-AKI from May 1st, 2020, to April 30th, 2021. Kidney replacement therapy (KRT), recovery of kidney function, and death at 90-day and 1-year follow-up were evaluated.
results360 patients were included, 60.6% were male, median age was 66.0 (57.0-72.0) years, 38.1% had diabetes, and 68.6% had hypertension. AKI stages 1, 2, and 3 were detected in 3.6%, 5.6%, and 90.8% of patients, respectively. KRT was indicated in 90% of patients. At the 90-day follow-up, 88.1% of patients died and 10.0% had recovered kidney function. Female gender (p = 0.047), older age (p = 0.047), AKI stage 3 (p = 0.005), requirement of KRT (p < 0.0001), mechanical ventilation (p < 0.0001), and superimposed bacterial infection (p < 0.0001) were significantly associated death within 90 days. At 1 year, mortality was 89.3%. Amongst surviving patients, 72% recovered kidney function, although with significantly lower eGFR compared to baseline (85.5 ± 23.6 vs. 65.9 ± 24.8 mL/min, p = 0.003).
conclusionCritically ill COVID-19 patients with NC-AKI presented a high frequency of AKI stage 3 and KRT requirement, with a high 90-day mortality. Surviving patients had high rates of recovery of kidney function, with a lower eGFR at one-year follow-up compared to baseline.
