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

introductionCytokine storm is one of the consequences of the severe forms of COVID-19 due to excessive immune response. In this study, we investigated the therapeutic effect of plasmapheresis and its role on the inflammatory cytokines levels in patients suffering from severe COVID-19.

methodsIn plasmapheresis group, 22 severe cases of COVID-19 receiving three cycles of plasmapheresis with time interval of 24-36 h and 22 COVID-19 patients as the control group were enrolled. Clinical history and laboratory parameters as well as IL-1, IL-6, IFN-γ and IL-17 cytokines serum levels in the time points of before and after plasmapheresis were studied.

resultsIn severe COVID-19 patients, plasmapheresis significantly improved clinical and laboratory parameters such as cough, weakness, fever, blood oxygen saturation and CRP levels. Serum levels of IL-1, IL-6, IFN-γ and IL-17 in the group of patients receiving plasmapheresis, had a significant decrease following plasmapheresis courses. Although only IL-6 level in the control group had a significant decrease between the days 1-14 of disease. Also, at both time points of before and after plasmapheresis, serum levels of IL-1, IL-6, IFN-γ and IL-17 were inversely correlated to blood oxygen saturation.

conclusionBased on the obtained results, plasmapheresis therapy in severe forms of COVID-19 can effectively improve the clinical symptoms of the disease and reduce inflammatory markers. Therefore, it is suggested that plasmapheresis can be evaluated in standard treatment protocols for severe forms of COVID-19.
