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 aim of the present study was to evaluate of the right and left heart mechanics by two-dimensional (2D) speckle tracking echocardiography (STE) in chronic thromboembolic pulmonary hypertension (CTEPH) patients before and after pulmonary thromboendarterectomy (PTE). A total of 40 consecutive CTEPH patients (mean age 49.3 ± 13.5 years, 27 female) were included. 2D STE was performed in all patients before, and 3 months, after PTE. 12 months of prognostic data were also recorded via the use of telephone calls. Postoperative 6-minute walk test (6MWT) distances were significantly longer than preoperative values (410.5 ± 61.5 vs. 216.6 ± 131.4 m, p < 0.001). Postoperative left ventricular (LV) and right ventricular (RV) systolic functions (LV EF, TAPSE, RVS) were similar compared to preoperative values. While postoperative RV, right atrial (RA) and systolic pulmonary artery pressure measurements were significantly lower, LV and left atrial (LA) measurements were higher than preoperative values. Postoperative LV and RV global longitudinal strain (GLS) measurements were significantly higher than preoperative values. Postoperative LV global radial and circumferential strain measurements were similar to preoperative values. While postoperative RA reservoir and conduit functions were significantly higher, postoperative LA reservoir and conduit functions were similar to preoperative values. Correlation analysis revealed that baseline 6MWT distances were correlated with LV GLS, RV GLS, and RA reservoir and conduit functions in the preoperative and postoperative periods. 2D STE indices may help the clinician in assessing the effect of PTE on cardiac functions and may also be used for follow-up data in CTEPH patients.
