1 · What the graph read from 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.

2 · The registry

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

backgroundCentral vein cannulation is a common invasive procedure performed in critically ill patients and during major surgeries. This study compares the right internal jugular vein's diameters and cross-sectional area after passive legs elevation and hepatic compression, analyzing these based on age, gender, body mass index and fasting duration.

methodsA cross-sectional study of 184 elective surgery patients (84 males, 84 females) at B.P. Koirala Institute of Health Sciences, Nepal, included 18-75 years. EXCLUSIONS: patients on mechanical ventilation, history of right jugular cannulation, neck/abdominal swelling, raised intracranial pressure, lower extremity fracture and refusal of consent. Age, gender, fasting duration and body mass index were recorded. The 6-13 MHz linear probe identified the internal jugular vein by its compressibility and anechoic appearance. Short axis view of transverse and anteroposterior diameters and cross-sectional area were measured in short axis view at the cricoid level using electronic calipers. Maximum diameter and average cross-sectional area were measured in supine with the head rotated 15°- 30° left, after one minute of passive legs elevation at 45° and after hepatic compression for one minute with a 19.6 N force.

resultsHepatic compression increased transverse diameter by 1.64 (0.40) cm, p = 0.035 and cross-sectional area by 1.28 (0.54) cm

conclusionHepatic compression better optimizes transverse diameter and cross-sectional area of right internal jugular vein than passive legs elevation.
