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: Blood compatibility of cardiovascular implants is still a major concern. Rapid endothelialization of these implant surfaces has emerged as a promising strategy to enhance hemocompatibility and prevent complications such as thrombus formation and restenosis. The successful endothelialization of implant surfaces mostly depends on the migration of endothelial cells (ECs), the differentiation of stem cells, and the inhibition of smooth muscle cell (SMC) proliferation. Our previous study demonstrated that nanostructured titania surfaces modified with polyelectrolyte multilayers based on tanfloc (a cationic tannin derivative) and glycosaminoglycans (heparin and hyaluronic acid) have improved antithrombogenic properties. Methods: In this work, we used in vitro cell culture of ECs and SMCs to investigate the outcomes of these surface modifications on endothelialization. The cells were seeded on the surfaces, and their viability, adhesion, and proliferation were evaluated after 1, 3, and 5 days. Indirect immunofluorescent staining was used to determine the cellular expression of ECs through the presence of specific marker proteins after 7 and 10 days, and EC migration on the NT surfaces was also investigated. Results: The surfaces modified with tanfloc and heparin showed enhanced EC adhesion, proliferation, and migration. However, SMC proliferation is not promoted by the surfaces. Therefore, these surfaces may promote endothelialization without stimulating SMC proliferation, which could improve the hemocompatibility without enhancing the risk of SMC proliferation leading to restenosis. Conclusions: The surface modification here proposed is a promising candidate to be used in cardiovascular applications due to enhanced antithrombogenic and endothelialization properties.
