Systemic sclerosis complicated by chronic thromboembolic pulmonary hypertension treated with balloon pulmonary angioplasty: a case report.

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
backgroundSystemic sclerosis (SSc) is known to induce pulmonary hypertension (PH), resulting in poor prognosis. Pulmonary hypertension secondary to connective tissue disease is usually classified as Group 1. In patients with SSc, PH owing to left heart failure (Group 2) and interstitial pneumonia (Group 3) are also known; however, there have been limited reports on chronic thromboembolic PH (CTEPH), which corresponds to Group 4. CASE SUMMARY: A 39-year-old female with SSc was admitted with shortness of breath on exertion for the past 4 months. Right heart catheterization revealed severe PH. Group 1 PH secondary to collagen tissue disease was suspected; however, thoracic computed tomography and lung perfusion scan led to the diagnosis of CTEPH of Group 4. We treated the PH with several medications and balloon pulmonary angioplasty (BPA), which improved the PH and right heart failure. Consequently, her overall condition also improved. DISCUSSION: This is a rare case report of SSc complicated by CTEPH, which was treated with BPA. Patients with SSc are prone to complications of various type of PH. Thus, it is important to distinguish CTEPH in terms of treatment choice and prognosis.
