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
Background and Aims: Flexible GI endoscopy has been applied in the field of gynecology. GI endoscopy is useful in diagnosing uterine cervical cancers, because high-resolution imaging using magnification enables targeted biopsies. Moreover, hemostasis for uterine cancer using GI endoscopy and hemostatic forceps, as well as the local treatment of vaginal intraepithelial neoplasia, have been achieved. Methods: In the present case, hemostasis for arteriovenous malformation using argon plasma coagulation was attained with transvaginal endoscopy. Results: An 85-year-old female patient presented to our hospital for admission with intermittent rectal and genital bleeding. She had previously undergone concurrent chemoradiotherapy for cancer of the uterine body, at 45 years of age. Furthermore, she had undergone a colostomy and urostomy for a vesico-rectovaginal fistula, in her 70s. The source of the bleeding could not be identified by contrast-enhanced abdominal computed tomography, cystoscopy, vaginal examination, or rectal endoscopy. Spontaneous hemostasis was achieved; nevertheless, she was readmitted to our hospital because of a recurrence of symptoms and progressively worsening anemia. Vaginoscopy revealed blood in the vagina; however, the source of bleeding was not detected, particularly by subsequent rectal endoscopy. An oozing from arteriovenous malformation near the vesico-rectovaginal fistula was identified by transvaginal endoscopy. Hemostasis was achieved, using argon plasma coagulation. No recurrence of bleeding was observed after endoscopic hemostasis. The absence of symptomatic recurrence was confirmed at the 1-month follow-up, after discharge. Conclusions: In this case, transvaginal endoscopy revealed the source of bleeding that was in the blind spot, during rectal endoscopy. This case highlighted that further applications using flexible GI endoscopy in the field of gynecology should be investigated.
