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

aimsThis study aimed to evaluate the prognostic value of segment involvement score (SIS) from coronary computed tomography angiography (CCTA) and compare it with coronary artery calcium score (CACS) in clinical practice. METHODS AND

resultsPatients undergoing CCTA for suspected coronary artery disease between 2006 and 2022 at 27 centres were included. SIS was defined by the number of segments with plaque. CACS was calculated using the Agatston method. Patients were followed for all-cause death and/or myocardial infarction (MI). A total of 23,034 patients were followed for a median of 2.5 years. SIS = 0 was found in 61.4% of patients, SIS = 1 in 12.6%, SIS = 2 in 8.2%, SIS = 3 in 5.7%, and SIS ≥ 4 in 12.2%. Compared with SIS = 0, SIS ≥ 4 was associated with higher adjusted risk of death (HR [95% CI]: 1.39 [1.17-1.66]), MI (3.53 [2.72-4.59]), and death or MI (1.88 [1.62-2.18]). Obstructive stenosis (≥50%) was also independently associated with all outcomes but showed lower discrimination than SIS in receiver operating characteristic curve analyses. SIS and CACS had similar ability to predict death or MI (Area under the curve: 0.70 [0.67-0.74] vs. 0.68 [0.65-0.72], P = 0.08) and MI alone (0.72 [0.67-0.77] vs. 0.72 [0.67-0.78], P = 0.69). CACS performed better than SIS in predicting death (0.70 [0.66-0.74] vs. 0.67 [0.63-0.70], P = 0.008).

conclusionBoth the extent of coronary atherosclerosis, measured by SIS, and the presence of obstructive disease are important predictors of outcomes. However, they do not provide additional prognostic value over CACS when used in routine clinical practice.
