Prevalence and risk prediction value of tricuspid regurgitation by echocardiography in precapillary pulmonary hypertension.
Article in BMC pulmonary medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundIn precapillary pulmonary hypertension (PH), the incidence of different tricuspid regurgitation (TR) degree is poorly defined. The impact of TR severity on pulmonary artery pressure (PAP) assessment and clinical risk stratification in precapillary PH remains unclear.
methodsA total of 207 patients diagnosed precapillary PH who underwent right heart catheterization (RHC) and echocardiography within 3 days were included. The severity of TR was graded as trace, mild, moderate and severe. Pearson correlation analysis was performed to evaluate the correlation between systolic PAP by echocardiography (sPAP
resultsThe proportion of None, Trace, Mild, Moderate and Severe TR group was 2.4%, 23.7%, 39.1%, 28.5% and 6.3% respectively. Right atrium (RA) area increased gradually with TR aggravation (p < 0.001). Moderate and Severe TR group had higher N-terminal pro-B-type natriuretic peptide (p < 0.001), right atrial pressure (RAP) (p = 0.018), right ventricular basal diameter (RVD)/left ventricular basal diameter (LVD) ratio (p < 0.001), larger right ventricle (RV) (p < 0.001) and lower tricuspid annular plane systolic excursion (p = 0.006) compared with Trace and Mild group. TR-sPAP
conclusionsPrecapillary PH was not necessarily accompanied by significant TR. None or Trace TRaccounted for 26% in our population and TR-sPAP
