Pingyangmycin Pretreatment Influences the Biological Behavior of Ocular Venous Malformation and Relates with Galectin-3 Expression.
Article in Chinese medical journal, 2017. 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
backgroundGalectin-3 (Gal-3) plays a role in the mechanisms underlying ocular venous malformation. We conducted this study to investigate the effect of pingyangmycin pretreatment on the Gal-3 expressions and biological behavior of ocular venous malformation.
methodsTissue samples were collected from 136 patients with ocular venous malformation. Patients were randomly divided into pingyangmycin (n = 69) and nonpingyangmycin group (n = 67). Patients in the pingyangmycin group received a local injection of 0.02% pingyangmycin once every 2 days for 2 weeks (7 doses) before removal surgery, whereas patients in the nonpingyangmycin group underwent removal surgery without local injection. The protein and messenger RNA (mRNA) expression of Gal-3 were detected by using immunohistochemistry and in situ hybridization.
resultsGal-3 protein was expressed in 35 (52%) of 67 samples in the nonpingyangmycin group and in 19 (28%) of 69 samples in the pingyangmycin group (P < 0.05). Gal-3 mRNA expression was detected in 39 (58%) of 67 samples in the nonpingyangmycin group and 22 (32%) of 69 samples in the pingyangmycin group (P < 0.05). The higher Gal-3 expressions were detected in samples with deeper invasiveness than those with superficial invasiveness before (χ2 = 12.720 and 13.369, respectively, both P < 0.05) and after pingyangmycin treatment (χ2 = 8.429 and 4.590, respectively, both P < 0.05). It was more frequently detected in mesh-like lesions with unclear boundary than round lesions with clear boundary before (χ2 = 30.291 and 41.466, respectively, both P < 0.05) and after pingyangmycin treatment (χ2 = 14.619 and 15.130, respectively, both P < 0.05). Pingyangmycin treatment led to a significant difference in Gal-3 expressions at both protein and mRNA levels (χ2 = 8.664 and 9.524, respectively, both P < 0.05).
conclusionsGal-3 expression may be involved in the development and invasiveness of ocular venous malformation, and pingyangmycin can inhibit Gal-3 expression, indicating a role of pingyangmycin treatment before the removal of ocular venous malformation.
