Left Ventricular Global Longitudinal Strain in Patients With COVID-19 Infection.
Article in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2, is an ongoing pandemic that has affected millions globally. Many infected patients have been noted to have cardiovascular damage. Prior to the development of clinical symptoms, the use of transthoracic echocardiography, specifically with measurements of left ventricular global longitudinal strain (LVGLS), may provide an additional prognostic marker for patients infected with COVID-19. We sought to determine whether patients with COVID-19 and reduced LVGLS have an increased risk for mortality. The mean LVGLS was determined to be significantly lower in the non-survivors compared to the survivors (-11.6 ± 1.8 vs -15.4 ± 0.74, p<0.05). It should be noted, however, that even those that survived were found to have reduced LVGLS (<-18.5%). A multivariate logistic regression analysis was also performed that demonstrated a relationship between reduced LVGLS and an increased risk for mortality. Overall, our data indicate that COVID-19 patients may have subclinical left ventricular dysfunction, and that critically ill patients may have a greater decline in cardiac dysfunction.
