Prediction of fractional flow reserve with angiographic DILEMMA score.
Article in Anatolian journal of cardiology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveAngiographic assessment of stenosis has limited predictive value for functionally significant lesions compared with fractional flow reserve (FFR). The recently developed angiographic DILEMMA score, which consists of minimal lumen diameter (MLD), lesion length (LL) and Bypass Angioplasty Revascularization Investigation (BARI) Myocardial Jeopardy Index (MJI) was found to have diagnostic value in predicting FFR ≤0.80. The present study was an investigation of prediction of FFR ≤0.80 using DILEMMA score and its relationship to resting distal coronary artery pressure/aortic pressure (Pd/Pa).
methodsRecords of consecutive patients who underwent coronary angiography and FFR were retrospectively analyzed. Assessment of MLD and LL was performed using quantitative coronary angiography. BARI MJI was calculated using angiographic calculation index.
resultsA total of 185 pressure wire analysis data sets from 150 patients were analyzed retrospectively. There were 82 lesions in FFR >0.80 group and 103 lesions in FFR ≤0.80 group. Negative correlation was found between FFR and DILEMMA score (r=-0.494; p<0.001), FFR and BARI-MJI (r=-0.378; p<0.001), and between FFR and LL (r=-0.314; p<0.001). Positive correlation was found between FFR and baseline Pd/Pa (r=0.713; p<0.001), and between FFR and MLD (r=0.415; p<0.001). DILEMMA score had negative correlation with resting Pd/Pa (r=-0.389; p<0.001). In receiver operating characteristic analysis for diagnosing FFR≤0.80, area under curve values of resting Pd/Pa, DILEMMA score, MLD, BARI-MJI, and LL were 0.862, 0.793, 0.780, 0.728, and 0.686, respectively.
conclusionDILEMMA score had moderately strong correlation with FFR and good accuracy in diagnosing significant FFR, but it had weak correlation with resting Pd/Pa.
