Use of strain imaging to detect subtle myocardial involvement in post COVID-19 patients: An Indian perspective.
Article in Indian heart journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe study assessed Global longitudinal strain imaging (GLS) to detect subtle myocardial dysfunction among patients clinically recovered from COVID-19.
methodsAll patients (n = 101 76 % males, mean age 55.45 ± 11.14 years), and controls (n = 30), underwent clinical assessment and echocardiography, including GLS assessment.
resultsThe prevalence of diabetes mellitus, hypertension and dyslipidemia was comparable amongst patients and controls. The average GLS was significantly lesser in post COVID patients (-16.21 ± 1.96 vs -18.49 ± 1.64 respectively, p = 0.004) and significantly higher proportion of post COVID patients had GLS > -18 % (43 % vs 22.58 % respectively, p = 0.001) as compared to controls. The RV free wall longitudinal strain (RVFLS) was also lower in the patient group (22.35 ± 4.69 vs 24.19 ± 4.11, p = 0.004) and 21.7 % post COVID-19 patients had pathological RV FWLS (> -20 %) vs controls (6.6 %). Average GLS was significantly lesser in severe post COVID patients (viz -14.25 ± 1.92 vs -16.63 ± 1.61 vs -17.63 ± 1.91, p < 0.0001, respectively among severe, moderate and mild COVID-19 patients. On performing regression analysis, severity of COVID-19 (OR 7.762) was a significant predictor of impaired GLS.
conclusionDespite normal global LVEF, post COVID-19 recovered patients had significantly lower LV GLS and RV FWLS with severe COVID-19 infection, regardless of having a clinical recovery. This study reiterates the importance of speckle tracking echocardiography as an important imaging modality for detection of subclinical myocardial dysfunction in the post COVID-19 recovered patients.
