Effect of Funding Source on "Spin" in Studies of Ocriplasmin Therapy for Vitreomacular Traction and Macular Hole.
Article in Clinical ophthalmology (Auckland, N.Z.), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 examine the relationship between industry funding and "spin" in randomized controlled trials (RCTs) and meta-analyses investigating use of ocriplasmin for patients with vitreomacular traction (VMT) and macular hole (MH).
methodsIn this study, we examined all PubMed and Ovid MEDLINE RCTs and meta-analyses published in journals with impact factor ≥2 investigating effectiveness of ocriplasmin use for VMT and MH. The main outcome measure was correspondence between the studies' main statistical outcome and their abstract conclusion wording. Each article was reviewed by three independent observers and was evaluated for source of funding, industry co-authorship, study methodology, statistical significance of main outcome measure, correspondence between results of main outcome measure and abstract conclusion, and journal impact factor. Funding was determined by public disclosure. Discrepancies were resolved by consensus.
resultsTwelve studies met inclusion criteria, of which 11 were industry funded and 1 was non-industry funded; 11 (91.67%) showed correspondence between outcome and abstract conclusion, without difference between industry-funded and non-industry funded publications or between publications in journals with high impact factor (≥3) versus low impact factor (≥2 and <3).
conclusionIn RCTs and meta-analyses of ocriplasmin for VMT and MH, our results suggest that neither industry funding nor journal impact factor affected the rate of "spin" in study conclusions. This study helps physicians understand what challenges they face when learning about a newer, less-established drug.
