1 · What the graph read from 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.

2 · The registry

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

backgroundFully automated diagnostic echocardiography allows for broader screening, earlier diagnosis for patients with mitral regurgitation (MR). This feasibility study developed a deep learning (DL) framework to automatically detect MR in echocardiography videos and classify regurgitation samples into central or eccentric regurgitation.

methodsWe designed a Transformer-based deep learning model for fully automatic Doppler video detection of MR. This framework can automatically detect MR and classify central or eccentric regurgitation. The algorithm was trained, validated, and tested using retrospectively selected studies. A prospective dataset of 217 patients was used as an independent test database.

results(a) The model demonstrated exceptional diagnostic accuracy for MR, achieving accuracy rates of 0.94(95%CI: 0.90-0.97) and 0.92(95%CI: 0.89-0.96) in retrospective and prospective test sets, respectively, with area under the curve (AUC) values of 0.98 (95%CI: 0.96-1.0) and 0.97 (95%CI: 0.95-0.99). Its performance aligned with that of middle seniority physicians. (b) The model achieved an accuracy of 0.93 in identifying central and eccentric MR across both retrospective and prospective test sets, AUC values of 0.96 (95%CI: 0.89-0.99) and 0.95 (95%CI: 0.89-0.98), respectively. (c) On the tasks of MR, the diagnostic performance of the model in multiple views was better than that of the parasternal long-axis view (PLAX) alone or the apical four-chamber view (A4C) in both retrospective and prospective datasets.

conclusionThe Transformer-based algorithm proposed in this study can automate and improve the efficiency of clinical workflows, screen multi-view for the presence of MR, and assist in classifying regurgitation characteristics.
