Heterogeneity in disease activity, frequency of treatments, and visual outcomes among patients with retinal vein occlusion: relationship between injection need and vision with as-needed ranibizumab.
Trial report in The British journal of ophthalmology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
BACKGROUND/
aimsWe characterised the relationships between monitoring frequency, ranibizumab injection need and vision in patients receiving as-needed (pro re nata; PRN) ranibizumab for macular oedema due to branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO) in this post-hoc analysis of SHORE and HORIZON.
methodsPatients aged 18 years and older with macular oedema due to BRVO/CRVO were included in this analysis. Injection frequency and best-corrected visual acuity (BCVA) were evaluated by PRN injection frequency in the PRN dosing phase (months (M) 7-15) of SHORE and through 12 months of HORIZON. Prespecified PRN re-treatment criteria for each trial were based on protocol-prespecified BCVA and optical coherence tomography outcomes.
resultsAfter the initial 7 monthly ranibizumab injections, patients in SHORE gained a mean of 18.3 letters from baseline. Patients randomised to PRN, on average, maintained these gains. However, some patients experienced additional mean gains, whereas others suffered losses (range 4.0 (95% CI 0.7 to 7.3) to -4.6 (95% CI -11.8 to 2.6) letters in patients who received 0 and 6-7 PRN injections, respectively). In BRAVO and CRUISE (lead-in trials), patients experienced mean gains from baseline to M6 (monthly dosing) of 19.3 and 15.0 letters, respectively, with gains maintained with PRN from M6 to M12. However, mean BCVA changes from baseline to M12 varied in HORIZON (range -0.4 (95% CI -2.5 to 1.6) to -3.6 (95% CI -6.2 to -1.0) letters in patients who received zero and six injections, respectively, during the preceding PRN phase of BRAVO and CRUISE).
conclusionThe BRVO/CRVO population is heterogenous with a varied response to ranibizumab treatment.
