Morphological and Morphometric Study of Coronary Sinus in North Indian Population.

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
introductionCoronary sinus (CS) is the largest vein draining the blood from heart. It is a muscular tube of about 2 cm to 3 cm length and 1 cm in caliber. It has become a clinically important structure through its role in providing access for different cardiac procedures viz., biventricular pacing, arrhythmia ablation and for deployment of an array of cardiac devices.
aimTo study the location, shape, length and width of CS including its left atrial muscular coverage in 50 cadaveric hearts. MATERIALS AND
methodsThe present study comprised of 50 adult human apparently normal formalin fixed cadaveric hearts belonging to either sex obtained from the Department of Anatomy, Government Medical College, Amritsar, India. Location and shape of CS were noted, external and internal lengths of the CS were measured with the help of a thread and Vernier caliper. Width of CS was measured at three levels; at the beginning, at the point of entry of Middle Cardiac Vein (MCV) and at termination in right atrium. The walls of CS were examined to note whether they were covered by the muscles of left atrium or not. Descriptive analysis was done to calculate range, mean and Standard Deviation (SD) by using Statistical Package for Social Science (SPSS) 17.0.
resultsCS was located in the posterior atrioventricular sulcus in 98%. Two shapes; funnel in 82% and tubular/cylindrical in 18% were observed. External length of coronary sinus ranged from 20.5 mm to 58.78 mm (mean 38.22±8.6 mm) and internal length ranged from 16.28 mm to 49.6 mm (mean 34.48±8.9 mm). Maximum width of coronary sinus was at its termination (9.61±2.6 mm) and it was covered by muscles of left atrium in 96% of hearts.
conclusionCS is a constant structure in cardiac venous anatomy but its location, shape, length and width are variable. Knowing these variations can help cardiac surgeons especially during cardiac resynchronization therapy, ablation and defibrillation.
