Improved low-risk criteria scores for combination therapy of sildenafil and generic bosentan in patients with congenital heart disease with severe pulmonary hypertension: A prospective open label study.
Article in JRSM cardiovascular disease. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
objectiveWe evaluated the efficacy and safety of the bosentan as a sequential add-on therapy with sildenafil in pulmonary arterial hypertension with congenital heart disease (PAH-CHD) patients. MATERIAL AND
methodTwenty patients who were receiving sildenafil were given generic bosentan for up to a year. Hemodynamic data was collected from cardiac catheterization at pretreatment and at three months. Comparisons were made between the total scores of the four, low-risk criteria adapted from the 2015 ESC/ERS pulmonary hypertension guidelines, which are: 1) WHO functional class of I or II, 2) 6MWD of more than 440 m, 3) right atrial pressure of less than 8 mm Hg, and 4) cardiac index ≥2.5 L/min/m
resultsPatients' average age was 27 ± 11 years old (12-53). PVRi decreased from 16.7 ± 9.5 to 12.7 ± 10.3 Wood unit (WU) m2 (p = 0.025) and PVRi/SVRi decreased from 0.69 ± 0.33 to 0.49 ± 0.32 (p = 0.001). During the follow-up, the composite scoring of the low risk scores for 19 patients was increased significantly from 1.8 ± 1.0 at baseline to 2.3 ± 0.9 at 3 months, to 2.9 ± 0.8 at 6 months, and 3 ± 0.7 at 1 year (p = 0.001).
conclusionWe demonstrated intermediate term benefits for generic bosentan as an add-on therapy to sildenafil in patients with PAH-CHD by improving PVRi, and PVRi/SVRi at three months. A significant improvement was also seen in the combined scores of the low-risk criteria from below 2 to 3 at one year (p = 0.001).Thai Clinical Trials Registry (TCTR): TCTR identification number is TCTR20200506006.
