Evaluation of Subjective Assessment of Right Heart Size and Function Using Standard 2D-Echocardiographic Recordings in Horses With and Without Pulmonary Hypertension.

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
backgroundEchocardiographic evaluation of right heart (RH) size and function in horses is challenging and relies on subjective assessment.
objectivesEvaluate inter- and intra-rater agreement of subjective assessment of RH size, RH function, and the presence of pulmonary hypertension (PHT) in horses. Assess subjective RH changes with and without PHT and the influence of observer experience. ANIMALS: Healthy horses (n = 30) and horses with Doppler measurements suggesting the presence or absence of PHT (n = 30 each).
methodsNine standard echocardiographic recordings were analyzed by experienced (n = 4) and inexperienced (n = 5) observers. RH size, RH function, pulmonary artery (PA) size and distensibility, and the presence of PHT were subjectively assessed as normal, mildly, moderately, or severely changed. Inter- and intra-rater agreement was calculated using percentual agreement (% agree) and kappa (k). Sensitivity and specificity to detect PHT were calculated.
resultsOverall inter-rater agreement in all observers was low with 61% perfect agreement and k of 0.21; it was higher in experienced observers (k = 0.34, 77% agree) than in beginners (k = 0.18, 52% agree). Intra-rater agreement showed % agree > 80% in experienced observers (k = 0.35-0.76) and < 80% in beginners (k = 0.33-0.54). RH size and function were more commonly abnormal in the PHT group, with high specificity but low sensitivity to detect PHT. CONCLUSIONS AND CLINICAL IMPORTANCE: Rater agreement of subjective RH assessment was low and influenced by observer experience. Subjective absence of RH changes does not allow ruling out PHT, while the presence of characteristic RH changes suggests PHT.
