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
objectiveTo analyze the correlation between acute kidney injury (AKI) diagnosed by elevated serum creatinine (Scr) versus only meeting the urine output (UO) reduction criteria and short-term adverse outcomes in critically ill patients following non-cardiac surgery, and to evaluate the association between even mild elevations in Scr and clinical outcomes furthermore.
methodsThis study was a secondary analysis of data from a prospective cohort study. A total of 1020 non-cardiac surgery adults admitted to the intensive care unit (ICU) of Peking University First Hospital from May 20, 2019 to March 7, 2022 were included. According to Kidney Disease: Improving Global Outcomes (KDIGO) guideline, AKI patients were classified into two groups: the AKI-Scr group (those meeting the Scr elevation criteria) and the AKI-UO group (those fulfilling only the UO reduction criteria). The primary outcome was in-hospital mortality in patients with AKI, and the secondary outcomes were major renal adverse events, post-operative renal replacement therapy (RRT), postoperative complications, postoperative mechanical ventilation time, ICU stay, postoperative hospital stay, total hospital stay, and total medical costs. Multivariate Logistic regression analysis was used to identify risk factors of hospitalized death in critically ill patients with AKI following non-cardiac surgery.
resultsA total of 1020 non-cardiac surgical patients admitted to the ICU were enrolled, among whom 429 were diagnosed with AKI. There were 91 cases in the AKI-Scr group and 338 cases in the AKI-UO group. The primary study endpoint: no statistically significant difference in in-hospital mortality was observed between the AKI-Scr and AKI-UO groups (5.5%
conclusionIn critically ill patients with AKI following non-cardiac surgery, the short-term prognosis of patients with AKI whose diagnosis was mainly based on increased Scr was worse than patients who only met the diagnostic criteria of oliguria. Even a mild elevation in serum creatinine was associated with adverse patient outcomes.
