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: The aim of this study was to assess the efficacy of sozinibercept, a novel "trap" inhibitor of VEGF-C and VEGF-D, when combined with ranibizumab for the treatment of polypoidal choroidal vasculopathy (PCV). Design: Prespecified subgroup analysis of a randomized, double-masked, sham-controlled phase IIb trial. Participants: Adults with treatment-naïve neovascular age-related macular degeneration. Methods: Participants were randomized 1:1:1 to receive a total of 6 intravitreal injections of ranibizumab 0.5 mg given 4-weekly, in combination with either 0.5 mg sozinibercept, 2 mg sozinibercept, or sham injection (control). Active PCV was determined at baseline by masked readers at an independent imaging center based on multimodal imaging, including OCT (notched, sharply peaked, or multilobular pigment epithelial detachments with or without a ring of hyperreflectivity along the inner border), fundus photography (subretinal orange nodules), and fluorescein angiography (typical primarily occult multifocal lesions). Main Outcome Measures: The primary end point was mean change from baseline in best-corrected visual acuity (BCVA) through week 24. Secondary end points included categorical changes in BCVA from baseline, anatomical changes in lesion morphology, and safety. Results: Of 366 participants, PCV was identified in 66 (18%) using predefined criteria. Sozinibercept combination therapy produced a dose response, with a mean BCVA change from baseline to week 24 of +13.54 (2 mg, n = 22) and +10.87 (0.5 mg, n = 24) letters compared with +6.9 letters for ranibizumab (n = 20), respectively. The 2 mg sozinibercept combination group had a superior BCVA gain versus ranibizumab (+6.7 letter difference in least squares mean; Conclusions: In this predefined phase IIb subgroup of patients with PCV, sozinibercept combination therapy through inhibition of VEGF-C/-D achieved improved visual and anatomic outcomes compared with ranibizumab monotherapy consistent with the overall population.
