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
backgroundMany reports indicate that diabetes is one of the main risk factors for COVID-19 complications. Nevertheless, few studies have examined how DKA develops in T2DM patients who have SARS-CoV-2 infection.
objectivesThis study aimed to assess β-cell function, identify risk factors for DKA, and evaluate clinical outcomes in hospitalized patients with T2DM and COVID-19.
methodsA retrospective, single-center, case–control study was conducted at Ain Shams University Isolation Hospital from August 2021 to August 2022. The study included 70 adults with T2DM and confirmed COVID-19, categorized into two groups: 35 patients with DKA (cases) and 35 patients without DKA (controls). Clinical, laboratory, and outcome data were extracted from medical records.
resultsFasting C-peptide levels did not differ significantly between the DKA and non-DKA groups (median difference: −0.06 ng/mL, 95% CI − 0.28 to 0.16; p = 0.363), suggesting that absolute insulin deficiency was not the primary driver of DKA in this cohort. The DKA group was significantly older (mean difference: 9.8 years, 95% CI 4.2 to 16.0; p = 0.003) and had a longer median diabetes duration (median difference: 3.7 years, 95% CI 1.3 to 6.1; p = 0.009). These patients also presented increased levels of inflammatory and stress markers, including D-dimer (mean difference: 0.21 ng/mL, 95% CI 0.05 to 0.37; p = 0.020) and HOMA-IR (median difference: 1.93, 95% CI 0.45 to 3.60; p = 0.012). Mortality was significantly greater in the DKA group (22.9% vs. 0%, risk difference 22.9%, 95% CI 8.4% to 37.4%; p = 0.003).
conclusionIn patients with T2DM and COVID-19, DKA was not characterized by absolute insulinopenia but was associated with older age, longer diabetes duration, severe insulin resistance, and systemic inflammation. These factors contribute to significantly increased morbidity and mortality. Our findings highlight the multifactorial nature of DKA in this setting and underscore the importance of aggressive monitoring and management in high-risk patients.
