Early hematological indicators of severe COVID-19 disease in hospitalized patients: Data from a South Asian population.

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
introductionOutbreak of corona virus disease in 2019 (COVID-19) has resulted in significant morbidity and mortality worldwide. Our aim is to document hematological parameters of patients with COVID-19 during initial stage of diagnosis and to identify early hematological indicators of severe infection. MATERIALS AND
methodsThis retrospective study was conducted at Shifa International Hospital, Pakistan from April to November 2020. Patients hospitalized with COVID-19, diagnosed on RT-PCR and had a complete blood count (CBC) done within 48 hours of diagnosis were included. Data was analyzed using IBM
resultsA total of 425 patients were included in this study out of whom 272(64%) were males. The mean age was 55.61 ± 17.84 years. 95 patients (22.4%) had normal blood counts within 48 hours of COVID-19 diagnosis. Cytopenias were seen in 193(45.4%) patients. There were 75(17.6%) mortalities during the study period. Chi-square test showed that thrombocytopenia, lymphopenia and neutrophilic leucocytosis were significantly associated with mortality (P = .037, P < .001, P < .001 respectively) and need for ventilator (P = .009, P < .001, P < .001, respectively). Neutrophilia was also associated with development of Acute Respiratory Distress Syndrome (P < .001). On ROC analysis, Neutrophil-to-Lymphocyte Ratio yielded an area under the curve (AUC) of 0.693 and 0.660 for the outcomes mortality and need for ventilator, respectively. For a subset of 288 patients who had D-dimer levels checked within 48 hours of COVID-19 diagnosis, the AUC for mortality and ventilator need was 0.708 and 0.671, respectively.
conclusionHematological indices are vital indicators in the prognosis and risk stratification of COVID-19 during initial stages of disease.
