Incidence of lupus anticoagulant in hospitalized covid-19 patients.
Article in American journal of blood research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundProcoagulant profile of 2019-nCoV/SARS-CoV-2 has been well documented over the last year. Perturbance in coagulating factors has also been reported in Covid-19 patients, including increased d-dimers and reports of lupus anticoagulant (LA).
methodsThe current study aimed to identify the incidence of positivity of lupus anticoagulant in Covid-19 patients and analyze the association between LA and D-dimer in predicting thrombosis and mortality in one-hundred and five hospitalized adult (age >14 years) patients and forty-three hospitalized pediatric (age <14 years) patients with a confirmed diagnosis of Covid-19 between June 2020 and September 2020.
resultsTwenty-one (20%) adult patients were tested positive for PTT LA, of which nine (8.6%) turned out to be confirmed positive for LA through StaClot and DRVVT Ratio tests. Six (14%) pediatric patients were positive for PTT LA, and only one (2.3%) had positive StaClot. Median D-dimer at admission was positively correlated with age and CRP among adult patients and was significantly higher in expired cases (P=0.001). No association between any of the coagulation tests and thrombosis or mortality was observed in the pediatric cohort.
conclusionWe report an increased incidence of LA in Covid-19 patients, yet we didn't find any association between thrombotic events or mortality, probably due to the small sample size.
