1 · What the graph read from it

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.

2 · The registry

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

backgroundLymphopenia is one of features that helps identify patients with severe Covid-19. This retrospectively study analyzed the association of lymphopenia with the severity of COVID-19 infection, determinate the predictive factors of lymphopenia and the significance of mortality in patient with lymphopenia.

methodsThis retrospective study included patients diagnosed with Covid-19 and admitted to intensive care unit of our university hospital center From Mars 1st 2020, to December 31st

resultsIn this study, 589 patients were included, a group had lymphopenia with 357 cases (60.06%) and the non-lymphopenia group with 232 cases (39.4%). The median age of our patients having lymphopenia was 65 years (56-76). Hypertension and diabetes were noted in the majority of patients with lymphopenia than in the non-lymphopenia group. Lymphopenia was strongly correlated to the inflammatory biomarkers of COVID-19 and were significant. A significant correlation was found between lymphopenia group and CT scan. Lymphopenia was observed as an indicator of prolonged duration of hospitalization but was not significant.

conclusionAnalytical data from this retrospective study shows the importance in the association between lymphopenia and the severity of COVID-19 infection, hence the need for dynamic monitoring of the number of lymphocytes on admission and during hospitalization of these patients.
