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
objectiveThis study was conducted to determine whether the presence and degree of left ventricular diastolic dysfunction (LVDD) can be predicted by the simple computed tomography -measured left atrial diameter (CTLAD).
methodsAmong adult patients who underwent both chest CT imaging and echocardiography in the emergency department from January 2020 to December 2021, a retrospective cross-sectional study enrolled patients in whom the time interval between the two tests was <24 hours. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic power of CTLAD for echocardiographic LVDD.
resultsIn a study involving 373 patients, 192 (51.5%) had LVDD. Among them, 122 (63.5%) had grade 1, 61 (31.8%) had grade 2, and nine (4.7%) had ≥grade 3. Median CTLAD values were 4.1 cm for grade 1, 4.5 cm for grade 2, and 4.9 cm for ≥grade 3. The area under the ROC curve value of CTLAD in distinguishing ≥grade 1, ≥grade 2 (optimal cutoff ≥4.4 cm), and ≥grade 3 (optimal cutoff ≥4.5 cm) were 0.588, 0.657 (sensitivity, 61.4%; specificity, 66.0%, positive predictive value, 29.5%; negative predictive value, 88.1%; odds ratio, 3.1), and 0.834 (sensitivity, 88.9%; specificity, 70.1%; positive predictive value, 6.8%; negative predictive value, 99.6%, odds ratio, 18.7), respectively.
conclusionCTLAD ≥4.4 cm can be used as a rough reference value to distinguish LVDD of ≥grade 2, while CTLAD ≥4.5 cm can reliably distinguish LVDD of ≥grade 3. CTLAD might be a useful parameter for predicting LVDD in situations where echocardiography is not available.
