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
backgroundSerum lactate is a key biomarker of tissue hypoperfusion and metabolic stress in sepsis. Although lactate clearance is widely recognized, many intensive care units record only a peak lactate within 24 h (pLac-24h). The prognostic value of pLac-24h among patients receiving blood purification therapy remains unclear in Asian intensive care settings.
methodsWe retrospectively analyzed the 2018-2020 ICU dataset from MacKay Memorial Hospital, Taiwan. Among 16,693 adult ICU admissions, 2506 patients received continuous renal replacement therapy (CRRT) as blood purification for severe sepsis or septic shock. Of these, 1264 (50.4%) had available pLac-24h data, and 27 (1.1%) also required extracorporeal membrane oxygenation (ECMO). The primary outcome was 28-day all-cause mortality. Multivariate logistic regression adjusted for age, sex, APACHE II score, infection source, and CRRT/ECMO use. Discrimination was evaluated by receiver operating characteristic (ROC) curves and decision-curve analysis. This analysis was conducted as a predefined sub-analysis of an institutional ICU database.
resultsThe mean age of the cohort was 65.7 ± 13.4 years, and 64.8% were male. Median pLac-24h was 5.1 mmol/L (IQR 3.2-8.6). The overall 28-day mortality among CRRT patients was 47.3%. Mortality rose progressively across pLac-24h quartiles (Q1-Q4: 28.9%, 39.4%, 54.7%, and 68.1%;
conclusionsIn critically ill patients with septic shock undergoing CRRT, peak lactate within 24 h was a strong, independent predictor of 28-day mortality. pLac-24h offers a pragmatic, readily available prognostic indicator when serial lactate measurements are unavailable, supporting its integration into bedside risk assessment in real-world Asian ICU practice.
