Diagnosis of Digital Ischemia During the COVID-19 Pandemic: A Study From a Developing Country.
Article in Cureus, 2025. 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
objectiveDigital ischemia (DI) is an uncommon condition. Information on the etiology of DI is limited. This study aimed to determine the diagnosis of DI in a tertiary care center in Bangladesh.
methodsThis cross-sectional study was conducted in the rheumatology department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, from September 1, 2020, to August 31, 2021. A total of 25 consecutive patients with DI were enrolled. Each patient was assessed following the classification/diagnostic criteria for vasculitis and vasculopathy. The 2012 International Chapel Hill Consensus Conference on the Nomenclature of Vasculitides was used for case definition. The study subjects were divided into vasculitis and vasculopathy groups. Fisher's exact and Student's t-tests were used to compare the groups.
resultsThe mean age was 35.88 years with a female predominance (72%). Among 25 patients, 15 (60%) were in the vasculitis group and 10 (40%) in the vasculopathy group. Takayasu arteritis was found in one subject (4%), and another 14 had vasculitis associated with connective tissue diseases: 11 (44%) lupus vasculitis, two (8%) rheumatoid vasculitis, and one (4%) associated with dermatomyositis. In the vasculopathy group, five cases (20%) had systemic sclerosis (SSc), four (16%) had peripheral arterial disease (PAD), and one (4%) had primary antiphospholipid syndrome (APS). Fever (p=0.01), arthralgia/arthritis (p=0.01), and high CRP (p=0.04) were significantly associated with vasculitis.
conclusionIn the hospital setting, connective tissue disease-associated vasculitis and SSc-related vasculopathy were the common causes of DI.
