Intravitreal ranibizumab alone or in combination with panretinal photocoagulation for the treatment of proliferative diabetic retinopathy with coexistent macular edema: long-term outcomes of a prospective study.
Trial report in Acta diabetologica, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled it.
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
aimsTo compare intravitreal ranibizumab as monotherapy or in combination with panretinal photocoagulation (PRP) in patients with proliferative diabetic retinopathy (PDR) and coexistent diabetic macular edema (DME) in a long-term follow-up of 24 months.
methodsParticipants in this prospective study were 47 patients with PDR and concurrent DME, who were randomized at baseline into two groups: (i) the "ranibizumab alone" group (n = 23), which was treated with at least 3 intravitreal ranibizumab injections as a loading phase, and (ii) the "combination" group (n = 24), which was treated with PRP and at least 3 intravitreal ranibizumab injections. Thereafter, all patients were followed up at a pro re nata (PRN) basis, with regular monthly monitoring for 24 months. At each visit, best corrected visual acuity (BCVA) and spectral domain-optical coherence tomography were performed, while regression of neovascularization was also recorded.
resultsThe "combination" group had better control of neovascularization and less events of vitreous hemorrhage than ranibizumab alone through the 2 years. BCVA did not differ significantly between the two groups at months 12 and 24 of the follow-up. The "ranibizumab" alone group presented greater reduction in central retinal thickness at month 12, which did not reach significance at month 24 compared to "combination" group. Greater number of injections was needed in the monotherapy group (mean 14 injections) compared to "combination" group (mean 11 injections) through month 24.
conclusionsBoth intravitreal ranibizumab alone or in combination with PRP could be used effectively for the treatment of PDR and coexistent DME. Even though there was no difference in BCVA and CRT at the 24-month follow-up between the two groups, the combination group presented greater regression of neovascularization with less injections.
