1 · What the graph read from it

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.

2 · The registry

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

backgroundAcute Pulmonary embolism (APE) is considered one of the deadliest cardiovascular diseases. Electrocardiographic (ECG) abnormalities in pulmonary embolism (PE) are increasingly reported. A growing number of studies have recommended that ECG plays a crucial role in the prognostic assessment of PE patients. However, there is scarce data on the prognostic importance of fragmented QRS (fQRS) on outcomes in patients with APE. This study aims to investigate the prognostic value of fQRS in APE patients. MATERIALS AND

methodsThis is a cross-sectional-analytic study. This study included 280 patients diagnosed with APE admitted to Shahid Madani hospital, Tabriz, Iran. Computed tomography pulmonary angiography (CTPA) was used to diagnose APE. A checklist was prepared for all patients, demographic, clinical characteristics, and Major Adverse Cardiopulmonary events (MACPE), including in-hospital mortality, need for thrombolysis, mechanical ventilation, and surgical embolectomy, were recorded. Patients were divided into two groups: patients who manifested fQRS on their ECG and patients who did not; Then, demographic, clinical characteristics, and MACPE were compared in the two groups, as mentioned earlier. Furthermore, all statistical analyses were carried out using SPSS software.

results48 patients (17.14%) had fQRS(+) on their ECG, and 232 patients (82.86%) did not have it on their ECG. In data analysis, 22 patients (8.7%) had in-hospital mortality, 35 patients (13.9%) needed thrombolysis, nine patients (3.9%) required mechanical ventilation, and 13 patients (5.1%) needed surgical embolectomy. fQRS was not significantly associated with in-hospital mortality (P = 0.225), need for thrombolysis (P = 0.684), mechanical ventilation (P = 1.000), and surgical embolectomy (P = 1.000). Demographic and clinical characteristics were also similar in both groups.

conclusionsThis study does not support the idea that fQRS on ECG is a valuable predictor of in-hospital mortality, the need for thrombolysis, mechanical ventilation, and surgical embolectomy.
