Body mass index and the risk of low femoral artery puncture in coronary angiography under fluoroscopy guidance.
Article in Medicine, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
The inferior border of the femoral head (IBFH) is widely used as a landmark in femoral artery puncture during invasive coronary angiography (ICA). However, application of this technique can be challenging especially in obese patients. This study was performed to investigate the association between body mass index (BMI) and the risk of low puncture in femoral artery puncture.A total of 464 patients (64.8 ± 11.1 years, 55.8% male) who underwent ICA via trans-femoral access were retrospectively reviewed. IBFH was used as a landmark for a skin nick and the femoral artery cannulation site was confirmed by femoral angiography. Cannulation at the bifurcation of the common femoral artery (CFA) or below were considered low puncture.Twenty-nine patients (5.8%) were identified as having an angiographically high CFA bifurcation and low femoral artery puncture occurred in 27 (93.1%) patients of them. Among patients with normal bifurcation (n = 464), low puncture occurred in 74 (15.9%) patients. Underweight (BMI < 18.5 kg/m) or obese (BMI ≥ 30 kg/m) patients were more common in the low puncture group than in the proper puncture group (36.5% vs. 5.9%, P < .001). Multivariable analysis showed underweight or obesity (odd ratio, 9.10; 95% confidential interval, 4.77-17.35; P < .001) was an independent risk factor of low puncture even after controlling for clinical covariates. The average distance from IBFH to the CFA puncture site was shorter in patients with underweight (1.74 ± 0.71 cm) or obesity (1.75 ± 0.60 cm) than in those with normal BMI or overweight (2.07 ± 0.83 cm) (P = .030). Trigonometric calculation showed that the average distance from IBFH to the CFA puncture site was 0.5 to 2.59 cm (mean = 1.32 cm) shorter in underweight patients compared with those of normal weight or overweight patients.In patients with normal CFA bifurcation, underweight or obesity were associated with increased risk of low puncture. The puncture site should be chosen about 1 finger width more proximal to IBFH for ICA in such patients.
