Correlation of Serum Calcium with Severity and Outcomes in Patients of COVID-19 Pneumonia.

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
Background: Calcium is an essential electrolyte with critical physiological functions. Recently, it has been implicated in the pathogenesis and outcomes of COVID-19. This retrospective study was conducted to estimate serum ionic calcium and its correlation with clinical severity, inflammatory markers, and in-hospital outcomes in moderate to severe COVID-19 patients. Methods: We retrospectively analyzed data from 377 COVID-19 patients, aged between 23 and 79 years, with a mean age of 54.17±11.53 years. Severity of the disease was determined using ICMR criteria. Parameters including age, gender, inflammatory markers, calcium levels, and clinical outcomes were assessed. Results: The study showed a prevalence of moderate and severe COVID-19 in 58.1% and 41.9% patients, respectively. Severity was significantly associated with younger age, higher mean inflammatory markers, notably IL-6, procalcitonin, D-Dimer, and lower ionic and total calcium levels, as well as vitamin D levels. Mortality and referral rate were significantly higher in the severe group. Hypocalcemia was prevalent in 39% of the patients and was significantly associated with disease severity, ARDS, and mortality. On multivariate assessment, only age and ionic calcium were significantly associated with COVID-19 severity. Conclusion: Lower serum ionic calcium levels are associated with increased severity and poor outcomes, including higher mortality in COVID-19 patients, underscoring the potential role of calcium as a diagnostic and prognostic marker in COVID-19 pneumonia and may be an important factor in various other forms of pneumonia.
