Outcomes of right heart dysfunction in the acutely and severely unwell: protocol for a prospective, longitudinal observational study using multimodal assessment.

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
introductionThe relationship of acute right heart dysfunction (RHD) with long-term cardiopulmonary dysfunction and its' associated morbidity has not been clearly elucidated. We propose a prospective, observational study to assess the natural history of acute RHD using a combination of imaging, functional and qualitative assessment methods, including the recently described combination of simultaneous maximal effort cardiopulmonary exercise testing and stress echocardiography. METHODS AND ANALYSIS: We propose a single-centre study of patients ≥18 years admitted to either the intensive care or respiratory close observation units with RHD on transthoracic echocardiography (TTE). Participants will undergo a repeat TTE ~72 hours after the initial study, with a final TTE performed prior to discharge in patients who have a prolonged (>1 week) stay. Inpatient clinical, biochemical and therapeutic indices will be collected contemporaneously. At ~6 months postdischarge, participants will undergo evaluation with validated symptom assessment tools (Dyspnoea-12 and PAH-SYMPACT Questionnaires) and a combined maximal effort cardiopulmonary exercise test and stress echocardiogram. This study is an observational, hypothesis-generating study with a recruitment target of 100 patients established based on typical admission rates of the relevant hospital departments. Measures of central tendency and dispersion will be used to describe the cohort. Inferential statistics will be used to compare the two a priori defined groups of those whose RHD had resolved prior to hospital discharge and those whose dysfunction persisted at time of discharge. ETHICS AND DISSEMINATION: This study has received ethics approval from the local ethics committee (Nepean and Blue Mountains Local Health District approval, project 2021/ETH12111). Written informed consent will be sought from all patients prior to recruitment. The results will be submitted for publication in a relevant peer-reviewed journal and presented at an appropriate national/international conference.
