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
introductionEarly identification of risk factors for acute respiratory distress syndrome (ARDS) in patients with coronavirus disease 2019 (COVID-19) is essential to guide preventive interventions. This study aimed to evaluate the predictive performance of hematological parameters measured at hospital admission for ARDS in pregnant and postpartum women with COVID-19. MATERIALS AND
methodsThis retrospective cohort study included all pregnant and postpartum women hospitalized with COVID-19 between March 2020 and October 2021. Demographic, clinical, and laboratory data were extracted from medical records. Total white blood cell (WBC), neutrophil, lymphocyte, and monocyte counts, as well as the neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR), were evaluated using receiver operating characteristic curve analysis, and the area under the curve (AUC) was calculated to assess their predictive performance for ARDS in these groups.
resultsA total of 126 patients were included, of whom 75.4% were aged 26-40 years. Overweight (37.8%) and obesity (45.9%) were the most frequent comorbidities. ARDS developed in 43.6% of patients, and 68.3% required invasive mechanical ventilation. Patients with ARDS had significantly higher WBC and neutrophil counts and lower lymphocyte counts (all p < 0.001). Both NLR and MLR were significantly associated with ARDS (p < 0.001). NLR showed the highest predictive performance for ARDS (AUC = 0.86) and a sensitivity of 81.5%. MLR demonstrated moderate predictive performance (AUC = 0.73) with a sensitivity of 63.0%.
conclusionsHematological parameters, particularly the NLR and MLR, measured at hospital admission may be useful for assessing the risk of ARDS in pregnant and postpartum women with COVID-19. Further studies are needed to establish the predictive performance of these parameters for ARDS in this population.
