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
backgroundExtubation failure is associated with an increased morbidity, emphasizing the need to identify factors to further optimize extubation practices. The role of biomarkers in the prediction of extubation failure is currently limited. The aim of this study was to investigate the prognostic value of cardiac (N-terminal pro-B-type natriuretic peptide (NT-proBNP), High-sensitivity Troponin T (Hs-TnT)) and inflammatory biomarkers (Interleukin-6 (IL-6) and Procalcitonin (PCT)) for extubation failure in patients with COVID-19 Acute Respiratory Distress Syndrome (C-ARDS). MATERIALS AND
methodsIn this single-center retrospective cohort study, patient characteristics and laboratory measurements were extracted from electronic medical records. Patients were eligible for inclusion if they were extubated after mechanical ventilation. The primary endpoint was extubation failure, defined as the need for reintubation or death within the next seven days after extubation, regardless of whether post-extubation respiratory support was used. Uni- and multivariable logistic regression was performed to investigate the association between biomarkers and extubation failure. Biomarkers were log
resultsOf the 297 patients included, 21.5% experienced extubation failure. In univariable analysis, NT-proBNP (OR 1.24, 95% CI 1.06-1.47), Hs-TnT (OR 1.72, 95% CI 1.37-2.19) and PCT (OR 1.38, 95% CI 1.16-1.65) measured on the day of extubation were significantly associated with extubation failure. After multivariable adjustment for clinical variables (age, duration of mechanical ventilation, SOFA score), Hs-TnT was the only biomarker that was independently associated with extubation failure (adjusted OR 1.38, 95% CI 1.02-1.90). Patients with both elevated Hs-TnT (≥ 14 ng/mL) and elevated PCT (≥ 0.25 ng/mL) carried the highest risk of extubation failure (46%), while in patients with normal Hs-TnT and PCT values, only 13% experienced extubation failure.
conclusionsHs-TnT, NT-proBNP and PCT measured on the day of extubation are associated with extubation failure in mechanically ventilated patients with C-ARDS. Since Hs-TnT is the only biomarker that is independently associated with extubation failure, Hs-TnT could offer additional objective measures for assessing readiness for extubation. Future studies should focus on an integrative approach of biomarkers combined with relevant clinical factors to predict extubation failure.
