Gender-associated dimensional differences among normal to non-flow limiting coronary artery dimensions.
Article in Indian heart journal, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
AIM AND
objectivesTo study gender-specific differences in coronary artery diameters among subjects with normal to non-flow limiting disease (NFLD) coronary arteries (up to 0 - 20% of stenosis) and to assess the possible association of body-mass index (BMI) with coronary dimensions, among the west coastal population of Karnataka and Kerala. MATERIALS AND
methodsA prospective cohort study was conducted for a period of one year. Two thousand angiograms samples were collected and assessed from two study centers (one from each state), after obtaining the ethical clearance. Patients with past history of myocardial infarction and those with recanalized normal looking coronary arteries and those who had diabetes for more than five years were excluded. Ten segments of coronary arteries- left main coronary artery, ostial and proximal segments of left anterior descending artery and its first diagonal branch, ostial and proximal segments of left circumflex coronary artery and its obtuse marginal branch, ramus intermedius and the ostial and proximal segments of the right coronary artery- were included in diameter measurement. BMI values of the patients were calculated.
resultsOut of 2000 patients included in the study, 454 (22.7%; mean age 53.4 ± 14.2 years) had normal to NFLD coronaries of which 253 (55.7%) were males and 201 (44.3%) were females. As compared to women, men had larger diameters of coronary arteries for eight segments, except the obtuse marginal branch and the proximal right coronary artery. A weak, yet statistically significant, negative correlation existed between BMI and coronary artery diameters in total cohort, indicating that an increase in BMI was associated with a decrease in artery diameters. No such association was seen when men and women were assessed separately.
conclusionsThe present study indicates that men have higher caliber for coronary arteries compared to women. The study also indicates that when BMI increases there is a relative decrease in the coronary artery diameter.
