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
backgroundRanibizumab has been widely used to treat retinal conditions such as wet age-related macular degeneration, diabetic macular oedema, and macular oedema secondary to retinal vein occlusions. In 2022, the Medicines and Healthcare products Regulatory Agency (MHRA) approved Ongavia, the first biosimilar of ranibizumab. Ongavia offers comparable efficacy and safety, with a similar side effect profile to the original medication, while being more cost-effective.
methodThe study was conducted in the medical retina department of a tertiary care eye hospital. Data were collected from patients undergoing treatment with intravitreal ranibizumab (Lucentis) who were switched to the ranibizumab biosimilar, Ongavia, between November 2023 and February 2024. This study included two components. The first was a cross-sectional observational survey, in which patients being switched to Ongavia completed a satisfaction questionnaire regarding the information leaflet received and the discussions held about the switch. The second component was a retrospective review to assess the effectiveness and safety of ranibizumab biosimilar Ongavia in patients with wet AMD. After two Ongavia injections, the treatment interval for the next injection was reviewed and compared with the treatment interval with ranibizumab. Similarly, OCT scans before and after the switch were reviewed and compared. Any adverse effects documented in the clinical notes were recorded.
resultsOut of 121 eyes, 92 eyes (76%) were switched to biosimilar ranibizumab (Ongavia) injections, while 18 eyes (15%) continued receiving ranibizumab injections. Patient satisfaction with the information process was 100%. Eighty-seven eyes of patients with wet AMD received more than two Ongavia injections as per the treat-and-extend protocol. Out of these 87 eyes, in 64 eyes (73.5%), injection intervals were either maintained or extended. The treatment interval was reduced in seven eyes (8%), and nine eyes (10.3%) were switched to a different anti-VEGF medication. No safety concerns were identified with biosimilar ranibizumab.
conclusionsPatient satisfaction with the information process was high, likely due to active involvement in treatment decision-making. The results indicate that the clinical effectiveness of ranibizumab biosimilar Ongavia is comparable to ranibizumab and that it has a similar safety profile. Ongavia could serve as a cost-effective alternative, reducing healthcare system costs while maintaining high standards of patient care.
