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

Background: Takotsubo syndrome (TTS) is a multifactorial disease contributed to by several pathological factors. It is characterized by transient left ventricular dysfunction, and patients with TTS can spontaneously recover within days or weeks. This study's objective was to investigate the ultrasonic characteristics of TTS during different periods and assess the clinical application value of real-time 3-dimensional echocardiography (RT-3DE) and speckle tracking imaging (STI) in TTS. Methods: In this prospective cohort study, the patients with apical TTS were evaluated by echocardiography on admission (within 1-3 days) and after 4 and 8 weeks. RT-3DE was performed to observe the structure and function of the left ventricle (LV). LV end-diastolic volume (LVEDV), end-systolic volume (LVESV), stroke volume (LVSV), and ejection fraction (LVEF) were calculated. The longitudinal peak systolic strain (LPSS) of all LV myocardial segments was acquired by 2D STI. For comparison, 20 healthy individuals were included as normal controls. Results: A total of 16 patients with TTS were included. Their LV was characterized as an "octopus pot" in morphology with obvious hypokinesis on admission. The LVEDV, LVESV, LVSV, and LVEF were 84.23±10.67, 55.94±8.51, 28.31±8.06 mL, and 33.59%±4.12%, respectively, in patients with TTS on admission with a significant difference from those of the controls (P=0.005, P<0.001, P<0.001, and P<0.001, respectively). A definite improvement was found upon follow-up, with these parameters even returning to normal morphology after 8 weeks. The LVEDV, LVESV, LVSV, and LVEF were 75.79±6.86, 28.05±4.33, 47.81±3.57 mL, and 63.02%±3.92%, respectively, in TTS patients after 8 weeks with no significant difference from those of the controls (P=0.907, P=0.235, P=0.162, and P=0.052, respectively). A significant decrease in LPSS was also found in patients with TTS on admission. In the eighth week of follow-up, the LPSS of the apical and middle segments in TTS patients remained significantly decreased compared with that of the normal controls (-18.54%±4.69% Conclusions: RT-3DE and STI played an indispensable role in visually and quantitatively inspecting the abnormalities of patients with TTS, including in diagnosis and follow-up.
