Routine Biomarkers for the Severity of COVID-19 Pneumonia May Present Differently in Kidney Transplant Recipients.
Article in Transplantation proceedings, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe treatment of coronavirus disease 2019 (COVID-19) is based on the patient's clinical status and levels of inflammatory biomarkers. The comparative activity of these biomarkers in kidney transplant (KT) patients with COVID-19 pneumonia from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and non-SARS-CoV-2 etiologies is unknown. The aim of this study was to compare the clinical presentation and inflammatory parameters at admission of KT patients with COVID-19 pneumonia and those with non-COVID-19 pneumonia over the same period.
methodsBiomarkers were measured and compared between KT patients with COVID-19 pneumonia (n = 57) and non-COVID-19 pneumonia (n = 20) from March 2020 to March 2021.
resultsBoth groups showed comparable demographics. The KT patients with COVID-19 had fewer neutrophils (6824 ± 5000 vs 8969 ± 4206; P = .09) than the non-COVID group, although there was no significant difference in the lymphocyte count. Non-COVID-19 pneumonia was associated with higher d-dimer (median, 921 [interquartile range (IQR), 495-1680] vs median, 2215 [IQR, 879-3934]; P = 0.09) and interleukin-6 (median, 35 [IQR, 20-128] vs median, 222 [IQR, 38-500]; P = 0.006) levels. The ferritin level was higher in the COVID-19 group (median, 809 [IQR, 442-1,330] vs median, 377 [IQR, 276-885]; P = 0.008). In multivariable analysis, only d-dimer (hazard ratio [HR], 1; 95% confidence interval [CI],1-1.002; P = .02) and ferritin (HR, 1; 95% CI, 0.9-0.9; P = .02) increase the statistic signification.
conclusionCOVID-19 pneumonia in KT patients shows a different presentation of inflammatory biomarkers than other non-COVID pneumonias. It could be useful to identify KT patients with COVID-19. More detailed studies are necessary to understand the presentation of biomarkers in KT with COVID-19.
