Serum vascular endothelial growth factor, insulin-like growth factor-1 and aflibercept levels in retinopathy of prematurity.
Article in Japanese journal of ophthalmology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo evaluate the serum levels of vascular endothelial growth factor (VEGF) and insulin-like growth factor-1 (IGF-1) after intravitreal injection of aflibercept (IVA) and the transition of aflibercept into systemic circulation in infants with severe retinopathy of prematurity (ROP). STUDY
designProspective study.
methodsThis single-centered prospective cohort study included infants who received IVA for the treatment of type 1 ROP in zone I and posterior zone II. Blood samples were collected before IVA and at 1 day and 1, 2, 4, and 8 weeks after IVA. VEGF, IGF-1 and aflibercept levels were measured.
resultsThirty eyes of 15 infants received IVA of 1 mg/0.025 mL. Serum VEGF levels decreased significantly at 1 day and 1, 2, 4, and 8 weeks after IVA compared with baseline (P < 0.05). Serum aflibercept levels decreased significantly 1, 2, 4, and 8 weeks after IVA compared with the level at 1 day after IVA (P < 0.05) and increased significantly at 1 day, 1, 2, and 4 weeks after IVA compared with the baseline level (P < 0.05). No significant difference was detected between serum IGF-1 levels any time in any infant (P > 0.05).
conclusionSerum VEGF levels are suppressed for at least 8 weeks, and aflibercept could be detected in the systemic circulation at 4 weeks after injection. Clinicians should be cautious about changes in systemic VEGF levels and passage of the agent into systemic circulation after IVA in infants.
