Impact on mortality at 90 days of acute kidney injuries in endovascularly treated stroke: A systematic review, meta-analysis, and meta-regression.

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
AimTo investigate the prognostic implication (mortality at 3 months) of acute kidney injury (AKI) in acute ischemic stroke treated with mechanical thrombectomy (MT).Material and MethodsA literature search was performed using PubMed/OVID/Cochran's CENTRAL database (time frame: inception to January 2023). Study characteristics, patient status, clinical outcomes, AKI incidence, and sample size were recorded. The exclusion criteria were non-English literature, no human subjects, and <10 patients as the sample size. Studies were assessed using the MINORS/GRADE system. Meta-analysis and meta-regression with a random-effects model were performed.Results3314 studies were retrieved. After applying the exclusion criteria, the final population included of 18/3314 studies (0.5%). Among them, only 6/18 (33.3%) studies reported results in two separate groups (AKI vs non-AKI), allowing for inference statistics for a total population of 3229 (538.6 ± 403.7). The I^2 was 34.6 and Q's Cochrane was 7.80. The pooled odds ratio (OR) for mortality at 3 months in patients with AKI was 5.8 (95% confidence interval [95% CI] 95% CI 3.62 to 9.52). Leave-one-out meta-analysis showed no significant sources of heterogeneity. In the meta-regression, diabetes prevalence was associated with a higher mortality rate (OR 1.14, 95% CI 1.03 to 1.28), and lower age and a small amount of contrast media were negatively correlated (0.91 [95% CI 0.83 to 0.99] and OR 0.97 [95% CI 0.94 to 1.00], respectively).ConclusionAKI was significantly associated with the mortality rate in MT-treated stroke patients (OR 5.8 [95% CI 3.62 to 9.36]).
