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
The present cross-sectional study investigated the clinical characteristics and survival of patients with three types of connective tissue disease associated with pulmonary hypertension (CTD-PH) diagnosed early by echocardiography. A total of 218 patients with CTD-PH were included in the present study. Patients with the three major types of CTD, namely systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and primary Sjögren's syndrome (pSS), were included. PH was diagnosed based on pulmonary arterial systolic pressure >35 mmHg, as measured by Doppler echocardiography. Demographic data, clinical features, laboratory results and echocardiographic parameters were collected and analyzed. The Kaplan-Meier method was used to calculate survival rates. Multivariate analysis was used to identify independent factors affecting mortality. Compared with patients with CTD with pSS (6.5%) or SLE (3.8%), those with SSc had a higher prevalance of PH (12.9%). Patients with SSc-PH had the highest rate of lung involvement (81.2%) and 42.2% of patients were classified as World Health Organization-function class III/IV at the time of diagnosis with PH. The overall survival rate among patients with CTD-PH at 1, 3 and 5 years was 81.4, 72.4 and 56.9%, respectively. Patients with SLE-PH appeared to have the most favorable prognosis and patients with SSc-PH had the poorest relative outcomes. Multivariate analysis revealed that age ≥50 years was the only independent risk factor for mortality. In conclusion, among the patients with CTDs investigated, the prevalence of PH was highest among those with SSc. Patients with SSc-PH had the highest prevalence of pulmonary involvement, the lowest survival rate and the worst prognosis.
