Article in International journal of general medicine, 2021. 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
objectiveTo observe hemodynamic characteristics in a series of patients with myocardial injury caused by severe COVID-19-related pneumonia. MATERIALS AND
methodsWe continuously collected clinical data from severe COVID-19-related pneumonia patients from the West Campus of Union Hospital in Wuhan and Dongguan People's Hospital in Dongguan to explore the prevalence of myocardial injury and hemodynamic characteristics after circulatory failure. Doppler ultrasound and PiCCO2 were used to evaluate the hemodynamics of each patient, and arterial blood gas analysis was performed at the same time. Pearson correlation analysis was used to clarify the relationship between the parameters.
resultsA total of 376 patients were observed during the study period. Eighty-seven patients had myocardial injury after admission, and the mean time of myocardial injury after admission was 6 (2, 30) days, from which 16 patients developed hemodynamic instability and 15 died of cardiogenic shock or combined with MODS. Cardiac echocardiography found that the LVEF of all patients was in the normal range and that diastolic function was slightly to moderately impaired. The PiCCO2 data showed that the GEF was significantly decreased in all patients. The dpmx was in normal range. EVLWI, SVRI and GEDI were significantly increased in most patients. Pearson correlation analysis showed that cTNI was significantly related to BNP at hemodynamic instability (r = 0.662, p = 0.005); GEF was related to EVLWI (r = -0.572, p = 0.021) and LAC (r = 0.692, p = 0.003); and EVLWI was affected by LVEF (r = -0.564, p = 0.023), LVDF (r = -0.734, p = 0.001) and PVPI (r = -0.524, p = 0.037).
conclusionHemodynamic status after myocardial injury and cardiogenic shock caused by severe COVID-19-related pneumonia was characterized by cardiac preload and increased EVLWI, accompanied by a decline in GEF.
