A Comparison of Transesophageal to Transthoracic Echocardiographic Measures of Right Ventricular Function.
Observational study in Journal of cardiothoracic and vascular anesthesia, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
objectivesTo assess the concordance between transesophageal echocardiographic (TEE) and transthoracic echocardiograpic (TTE) measures of right ventricular (RV) function using standard 2-dimensional and Doppler methods. The authors hypothesized that there would be significant disagreement in tricuspid annular plane systolic excursion (TAPSE), fractional area change, right-sided index of myocardial performance, and tricuspid annular systolic velocity (S').

resultsThe fractional area change, S', TAPSE, right-sided index of myocardial performance, and tricuspid annular diameter were measured with TEE and TTE to assess for concordance using the concordance correlation coefficient and paired t tests, including 95% confidence limits. The study demonstrated that quantitative measures of RV function by TEE correlate poorly with TTE measurements in close temporal proximity under similar hemodynamic conditions.
conclusionsWhen performing an assessment of RV function, transesophageal echocardiographers should exercise caution when extrapolating data validated by TTE to TEE studies. Measures of RV function by TEE tend to have fair agreement to TTE measurements obtained in close temporal proximity under similar hemodynamic conditions. Most importantly, the present study showed that TAPSE and S' values obtained from the modified transgastric RV inflow view tend to have lower values than those measured with TTE. Given the propensity for underestimating measurements from the modified transgastric RV inflow view, the authors conclude that values equal to or greater than established norms for tricuspid annular motion may be used to establish normal-but not abnormal-RV function.
