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
backgroundImpedance cardiography (ICG) offers a potential alternative for hemodynamic assessment in pulmonary arterial hypertension (PAH) as a non-invasive technique.
methodsA total of 132 patients who underwent right heart catheterization (RHC) were included. Cardiac output (CO) and stroke volume (SV) measured by thermodilution during RHC (COTD) and ICG (COICG) were compared. The capacity of ICG in PAH risk stratification and clinical deterioration prediction was also analyzed.
resultsNinety-three pre-capillary pulmonary hypertension patients were enrolled, 54 (58.06%) patients belong to Group 1 PAH, and 39 (41.94%) patients were diagnosed with chronic thromboembolic pulmonary hypertension. The mean COTD was 4.93 ± 1.06 L/min, while the COICG was 4.41 ± 1.23 L/min, showing a moderate correlation (r = 0.49, P < .001). In Group 1 PAH patients, the COTD was 5.13 ± 1.10 L/min, and COICG was 4.57 ± 1.22 L/min (r = 0.52, P < .001). Bland-Altman analysis indicated a mean difference of 0.52 L/min and limits of agreement from -1.76 to 2.80 L/min. The mean SVTD was 64.63 ± 17.10 mL, and the SVICG was 60.94 ± 18.03 mL (r = 0.53, P < .001) with a mean difference of 3.69 mL. After a 1-year follow-up, the CIICG and SVIICG showed potential power in predicting clinical deterioration in PAH patients, with area under the curves of 0.76 and 0.81, respectively.
conclusionImpedance cardiography measured CO and SV presented an acceptable correlation with RHC in PAH patients. Stroke volume index and cardiac index measured by ICG is potent to identify the low-risk status and predict clinical deterioration in PAH patients.
