Efficacy of an Indian Bevacizumab BIOSimilar (BEVATAS) for Type 1 and Aggressive Posterior Retinopathy of Prematurity (BIOS-ROP Study).
Article in Clinical ophthalmology (Auckland, N.Z.), 2024. 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
Purpose: To evaluate the role of an Indian bevacizumab biosimilar (Bevatas Patients and Methods: A retrospective, single-center, interventional study of 144 eyes of type 1 (100 eyes) and APROP (44 eyes). All eyes received a single dose of 0.625mg Bevatas injection, and were advised additional laser therapy for suboptimal response. Results: The study population had a mean gestational age of 28.94 (±2.32) weeks, an average birth weight of 1.2 (±0.34) kg, and modest male predominance (52.05%). Complete regression of ROP was seen in 65.97% of 144 eyes after 24 weeks of bevacizumab monotherapy, and in 97.22% of eyes (140 eyes) after adding laser photocoagulation. The remaining four eyes (all had APROP) developed Stage 4 ROP and needed vitreous surgery. After monotherapy with bevacizumab biosimilar, type 1 ROP eyes had significantly higher rate of complete ROP regression than APROP eyes (87% vs 18.18%; Conclusion: The BIOS-ROP study demonstrates that intravitreal bevacizumab biosimilar monotherapy offers significant benefit for type 1 ROP, but not APROP. Low-cost biosimilars can help sustain healthcare systems in lower-middle income countries (LMICs) with escalating healthcare expenditures. They can also improve healthcare equity by making vision-saving therapies like bevacizumab more affordable and accessible.
