Use of the myocardial performance index to assess right ventricular function in infants with pulmonary hypertension.
Article in Pediatric cardiology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
backgroundThis study aimed to measure and compare right ventricular (RV) function in normal infants and those with pulmonary hypertension (PHT) using the myocardial performance index (RVMPI) and to investigate the relationship between RV function and pulmonary artery pressure.
methodsA case-control study measured RVMPI in 16 infants with PHT (9 of whom had congenital diaphragmatic hernia) and 28 normal control infants. For the PHT infants, 43 paired measures of RVMPI and pulmonary artery pressure (estimated from tricuspid regurgitation jet velocity) were taken to allow investigation of the relationship between RVMPI and pulmonary artery pressure.
resultsThe mean RVMPI for the control infants was 0.24+/-0.09. The RVMPI was significantly elevated in the PHT group (0.55+/-0.17; p<0.0001), including a subgroup of infants with PHT secondary to congenital diaphragmatic hernia (0.58+/-0.18; p<0.0001). The correlation between RVMPI and pulmonary artery pressure in the infants with PHT (R2=0.05; p=0.17) was poor.
conclusionsIn infants, RVMPI allows quantification of right ventricular function and detection of RV dysfunction in PHT. No linear relationship exists between RVMPI pulmonary artery pressure. Use of RVMPI in the clinical setting must take into account the global and load-dependent nature of this measure.
