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
backgroundTransoesophageal echocardiography (TOE) provides accurate evaluation of mitral valve (MV) function following mitral transcatheter edge-to-edge repair (M-TEER) and may better detect complications in case of suboptimal result.
aimsWe aimed to evaluate midterm anatomical changes and structural complications after M-TEER using TOE and investigate their association with clinical outcomes at 2 years.
methodsA follow-up TOE at 6 months was systematically recommended to all patients included in our institutional prospective M-TEER registry until December 2021. We assessed changes in the incidence of mitral regurgitation (MR), MV stenosis (≥5 mmHg), and partial or complete single leaflet device attachment (SLDA) between the index procedure and follow-up and evaluated MV area and annular dimensions in a subset of patients with available three-dimensional (3D) datasets. The clinical endpoint was a composite of mortality and heart failure (HF) rehospitalisation at 2 years.
resultsAmong the 373 patients included in the registry between February 2012 and December 2021, 128 patients (34%) underwent elective TOE at 6 months. Using TOE, severe MR was observed in 13.3% (n=17) of the patients. The number of patients with an elevated MV gradient increased from 17 (13.3%) after the procedure to 23 (18%) at 6 months, and a new partial or complete SLDA was detected in 7.8% (n=10). Based on 3D TOE measurements, significant increases in MV area, annular area, annular perimeter, and intercommissural (but not anteroposterior) diameter were observed compared to intraprocedural images. A mean MV gradient ≥5 mmHg (hazard ratio [HR] 2.30, 95% confidence interval [CI]: 1.10-4.81; p=0.023) and the presence of severe MR at 6 months (HR 3.26, 95% CI: 1.18-8.99; p=0.023) were associated with the primary endpoint, which was met in 34 (26.6%) patients at 2 years.
conclusionsTOE follow-up allowed the detection of complications that would not be diagnosed using transthoracic echocardiography only and should therefore be used liberally in the patients presenting with a suboptimal result. A mean MV gradient ≥5 mmHg and severe MR, diagnosed at the 6-month TOE follow-up, were associated with adverse clinical outcomes.
