Ultrasonographic optic nerve sheath diameter for predicting elevated intracranial pressure during laparoscopic surgery: a systematic review and meta-analysis.
Synthesis in Surgical endoscopy, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07784361 (Assessment of Increased Intracranial Pressure by Optic Nerve Sheath Diameter), which is not on this map. Cited by 18 papers.
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.

Abstract
backgroundLaparoscopic surgery involves the creation of a carbon dioxide (CO
methodsA computerized literature search was performed in August 2016 to identity prospective studies that measured ONSD to assess ICP changes during laparoscopic surgery. The primary outcome was the change in ONSD during the early (0-30 min) and late (30-120 min) periods after initiating pneumoperitoneum, compared with baseline values measured after anesthesia induction. Mean differences (MDs) with 95% confidence intervals [CIs] were calculated.
resultsNine observational studies and one randomized controlled trial, with a total of 460 subjects, were analyzed. Compared to the baseline value after anesthesia induction, significant increases in ONSD were observed in both the early period (MD 0.46, 95% CI 0.31-0.61, P < 0.001, I
conclusionsThe current meta-analysis revealed that ICP elevation during laparoscopy could be anticipated through a significant increase in the ONSD in the early (0-30 min) and late (30-120 min) periods during CO
