IVUS determination of normal left main stem artery size and plaque burden, and correlation with body surface area in an Indian population.
Article in AsiaIntervention, 2022. 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
Background: There is a scarcity of data regarding the normal size of the left main stem coronary artery (LMS) in the Indian population; further data are needed to help determine the optimal device size during percutaneous coronary intervention (PCI). Aims: The aim of our study was to determine the normal size of the LMS and to calculate the mean plaque burden (PB) in the left main arteries which are angiographically normal or insignificantly diseased, using intravascular ultrasound (IVUS). We hoped to establish a correlation between LMS size and body surface area (BSA). Methods: We collected demographic and coronary artery data from 140 patients who underwent IVUS-guided PCI in the left anterior descending and circumflex arteries over a 2-year period from 2019 to 2020, where a pullback sequence of the LMS was available. The reference and luminal vessel diameters, the reference and luminal vessel areas and the mean plaque burden (PB) were obtained. Regression analysis was used to develop a correlation between BSA and LMS diameter. Results: The IVUS-determined mean reference diameter of the LMS was 5.53±0.63 mm and the mean luminal diameter was 4.62±0.65 mm. The mean reference vessel area was 24.79±5.5 mm Conclusions: The mean reference and luminal diameters of LMS in the Indian population are on par with the size of LMS in other ethnicities. The vessel compensates for up to 40% PB with vessel remodelling. Hence, a PB of 40% is a good landing zone for stent deployment.
