Efficacy of a chitosan tampon in the loop electrosurgical excision procedure: A prospective randomized controlled study.
Trial report in Scientific reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
It has been reported that chitosan has a hemostatic effect and an antibiotic activity. This study aimed to evaluate the efficacy and feasibility of using a chitosan tampon (Hemoblock-Tampon) in preventing hemorrhage and enhancing wound healing after the loop electrosurgical excision procedure (LEEP).This single-blind, prospective, randomized study included 62 consecutive patients who underwent LEEP for cervical intraepithelial neoplasia. A chitosan tampon (31 patients; treatment group), or a general tampon (31 patients; control group) was applied to the uterine cervix immediately after LEEP. One patient in the treatment group declined to participate in this study. Thus, 30 patients in the treatment group and 31 patients in the control group completed this study. For objective analysis of hemorrhage in the postoperative 2 weeks, the amounts of bleeding were checked daily with a pictorial blood assessment chart. We evaluated vaginal discharge, abdominal pain, and impairment in daily living during the postoperative 2 weeks using 5 visual analogue scale questionnaires.The bleeding count was significantly lower in the treatment group than in the control group (21.37 ± 16.86 vs. 40.52 ± 16.55, p = 0.0014). The sum of the scores of the 5 questionnaires was significantly lower in the treatment group than in the control group (6.53 ± 2.84 vs. 8.59 ± 2.88, p = 0.0079). The incidence of vaginal discharge was significantly lower in the treatment group than in the control group (20.0% vs. 48.4%, p = 0.0207). According to logistic regression, only the use of chitosan tampon reduced the risk of moderate to severe vaginal bleeding 2 weeks after surgery (Odd ratio, 0.213; 95% confidence interval, 0.06-0.76; p = 0.0172). Complete healing of the uterine cervix occurred in 86.7% of patients in the treatment group and in 61.3% of patients in the control group at 4 weeks after surgery (p = 0.0255).The use of chitosan tampons can reduce hemorrhage, vaginal discharge, abdominal pain, and impairment of daily living after LEEP. Moreover, chitosan tampon may help enhance wound healing.
