Anatomical variations of the left anonymous trunk are associated with central venous catheter dysfunction.

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
backgroundInternal jugular vein cannulation has become increasingly widespread. Compared to the left internal jugular vein (LIJV), the right internal jugular vein (RIJV) is the preferred choice for the placement of central venous catheter (CVC) for hemodialysis, mostly due to the major technical difficulties and higher rate of complications of the LIJV approach. We aimed to investigate whether variability in the direction of the LIJV/brachiocephalic vein (BV) axis on the frontal plane could be a decisive factor in determining CVC dysfunctions.
methodsRetrospective cohort study. From our Register, a total of 1489 consecutive patients (age 69 ± 9 years, males 60%) in whom a CVC for hemodialysis was placed from January 2012 to June 2014 were selected.
resultsLIJV cannulation, compared with RIJV, was associated with a higher rate of catheter dysfunction during an observational period of 2 weeks after catheter placement (16 vs.12%; p = 0.005). This complication was strongly correlated with the amplitude of the angle between the LIJV and the ipsilateral BV axis on the frontal plane; an angle ≤ 110° was associated with a higher rate of catheter dysfunction (78 vs.16%; p < 0.001).
conclusionsThe anatomical clarification presented in our study provides useful data that could explain the dysfunction rate of CVC inserted in the LIJV. Clinicians who insert high-flow catheters (such as hemodialysis catheters) should be aware of LIJV/BV axis variability and of the possible risks of CVC dysfunction when the angle between the LIJV and ipsilateral BV is ≤ 110°.
