Evaluation of the lymphocyte population and placental inflammation in pregnant patients with moderate or severe COVID-19 forms - a secondary analysis.

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
aimIn this secondary analysis, we aimed to characterize the lymphocytes population and placental inflammation in pregnant women with moderate and severe coronavirus disease 2019 (COVID-19) forms. PATIENTS, MATERIALS AND
methodsIn the analysis of this prospective evaluation, we included 26 pregnant women at term with moderate and severe COVID-19 forms that were evaluated in a tertiary maternity center in a one-year timeframe. Clinical data, along with blood immunophenotyping results and placental histopathological examinations were comparatively evaluated between two study groups depending on the COVID-19 severity: Group 1 (moderate COVID-19, n=14 patients) and Group 2 (severe COVID-19, n=12 patients).
resultsPregnant patients with severe COVID-19 presented significantly lower total amount of lymphocytes (p<0.001), T-lymphocytes (p=0.009), cluster of differentiation (CD)4+ T-cells (p=0.002), B-lymphocytes (p=0.001). Also, the number of CD4+ T-cells (p=0.01), CD8+ T-cells (p=0.02) and B-lymphocytes (p=0.002) was lower enough for cases with severe COVID-19.
conclusionsLymphocytopenia could be a useful hematological marker for risk stratification of COVID-19 in pregnant women at term. A vertical transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cannot be confirmed in this study, mainly because of the limited sample size and short timeframe between infection and birth.
