Real Life Data of Treat and Extend Intravitreal Ranibizumab and Aflibercept Therapy in Wet Age-related Macular Degeneration Patients: 3-Year Results.
Article in Korean journal of ophthalmology : KJO, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 compare functional and anatomic outcome of intravitreal ranibizumab (IVR) and intravitreal aflibercept (IVA) treatments in neovascular age-related macular degeneration by using the treat and extend (TE) protocol.
methodsIn this retrospective chart study, treatment naïve 74 eyes of 74 age-related macular degeneration patients treated with IVR and IVA (38 eyes in IVR and 36 eyes in IVA group) with TE protocol were included. Following three consecutive monthly intravitreal injections, TE protocol was applied to each group. Patients were followed up for at least 36 months. Mean change in best-corrected visual acuity (BCVA), central macula thickness (CMT) and injection numbers over 3 years were compared.
resultsAmong 36 months period, the mean number of injections was 17 ± 4 for both groups (p > 0.05). In terms of CMT, there was no statistically significant difference between groups at 36 months compared to baseline. A decrease of 72.55 ± 39.37 μm in CMT was detected in IVR group, whereas the decrease was 70.58 ± 33.96 μm in IVA group (p > 0.05). There was a significant increase in BCVA at 36 months of measurements. In addition, BCVA demonstrated an increase of 4.1 ± 0.44 letters in IVR group and 4.36 ± 0.67 letters in IVA group after 36 months compared to the baseline (p > 0.05).
conclusionsBoth IVR and IVA injections provided significant improvements and stability in BCVA and CMT, however there was no significant difference between IVR and IVA injections with TE protocol of 36 months.
