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
COVID-19 pandemic, which has exhibited a wide clinical spectrum and an unexpected surge in mucormycosis cases, understanding various biomarkers' roles becomes pivotal. As mucormycosis leads to clinical morbidity and mortality through angioinvasion and thromboembolism, unveiling the correlation between these markers and disease progression can shed light on the reasons behind mucormycosis's emergence as an epidemic, especially following the second wave of COVID-19. This long term ambispective observational study, conducted from May 2020 to July 2023, aimed to assess specific biomarkers as predictors of severity in COVID-19-associated mucormycosis (CAM). Biomarkers measured included ESR, CRP, D-dimer, IL-8, PCT, serum ferritin, and neutrophil-lymphocyte ratio (NLR) at different time points. Data analysis employed descriptive statistics, repeated measure ANOVA, Spearman correlations, ROC curve analysis, and logistic regression. Of 290 patients, 198 completed the 2-year follow-up. Elevated baseline biomarker levels significantly decreased with treatment initiation. CRP and NLR emerged as significant predictors of severe CAM, with odds ratio 2.926 (95% CI 1.466-4.360) and 2.203 (95% CI 0.863-1.040) respectively. Factors influencing CAM progression included age, CRP, and NLR, while all biomarkers independently predicted mortality. A death prediction model using CRP, PCT, D-dimer, NLR, and IL-8 demonstrated exceptional performance, with a sensitivity of 83.1% and specificity of 100%. Elevated inflammatory markers in CAM patients showed a decline with treatment, with NLR and CRP proving crucial for predicting severity. Serial monitoring of IL-8, CRP, PCT, NLR, D-dimer, and ferritin provides insights into disease progression and prognosis. The study underscores the importance of biomarker assessment in managing CAM, especially in the context of the unpredictable clinical spectrum of COVID-19 and the subsequent mucormycosis surge.
