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

purposeTo examine the effect of steep Trendelenburg position (ST) on intraocular pressure (IOP), resistive index of the central retinal artery, and venous impedance index of the central retinal vein during robotic prostatectomy and cystectomy.

methodsA total of fifty-three male patients were included into the study (prostatectomy: 43, cystectomy: 10). During robotic surgery, the effect of the ST on IOP, resistive index of the central retinal artery (CRA-RI), and venous impedance index of the central retinal vein (CRV-VI) was prospectively examined. The measurement times of IOP are as follows: T1: before anesthesia while supine and awake; T2: anesthetized and supine; T3: anesthetized and ST; T4: anesthetized, ST, and intraperitoneal insufflation; T5: anesthetized in ST at the end of the procedure with CO

resultsThere was no difference between the IOP values of the right and left eyes in both groups. The highest IOP values were reached at T4 and T5. CRA-RI values were different, while CRV-VI values were similar at T1 and T4.

conclusionsDespite staying in the ST for a long time provided that the ophthalmologic examination was normal, ocular complication risk is low in robotic prostatectomy and cystectomy.
