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
backgroundLong-term central venous catheter (CVC) insertion in dialysis patients is an accepted method of hemodialysis. The appropriate CVC tip placement may reduce both early and late complications related to catheter and increase patency rate. This study aimed to evaluate a new, simple, and feasible method based on surface anatomy for the proper placement of tunneled CVC in the left internal jugular vein for hemodialysis or chemotherapy. MATERIALS AND
methodsThe study was carried out as a quasi-experimental model at Saint Al-Zahra Education Hospital in 2016. A total of forty patients with an indication of left-sided (upper) long-term CVC insertion were enrolled. The length of catheter to be inserted in the left internal jugular vein was considered as the sum of distance from the insertion point of the needle up to sternal notch plus the total distance between the left and right sternoclavicular joint and half-length of the sternum. The right atrium (RA) or superior vena cava-RA junction was the correct region for inserting the catheter tip. The collected data were analyzed using Fisher's exact test and
resultsThe patients were 63.75 ± 17.96 years of age, weighed 67.33 ± 13.20 kg, and height of 166.92 ± 8.99 cm. Catheters were inserted successfully in 95% of patients (
conclusion"The mid - sternal length plus sternoclavicular joints spacing" as a new formula (based on anatomical landmarks) was found practical and safe and could easily be used among adult patients who undergo tunneled CVC in the left internal jugular vein.
