1 · What the graph read from it

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.

2 · The registry

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

Mature cystic teratoma of the fallopian tube is extremely rare, with no reports existing on infertility treatment following its surgical removal. We report a case of mature cystic teratoma identified within the right fallopian tube during laparoscopic surgery, with only the tumor resected while preserving the tube. Three-month postoperative hysterosalpingography showed preserved tubal patency, but contrast agent retention in the pelvic cavity was noted during the delayed phase, suggesting peritubal adhesions. Subsequent timed intercourse failed to result in pregnancy, leading to in vitro fertilization. Laparoscopy prior to embryo transfer confirmed hydrosalpinx, prompting right salpingectomy. Clinical pregnancy was achieved following frozen-thawed blastocyst transfer performed 2 months postoperatively. The pregnancy progressed well and resulted in delivery at term. Even when tubal preservation is chosen for mature cystic tubal teratoma, normal tubal function may not necessarily be maintained. Therefore, early postoperative hysterosalpingography and prompt laparoscopic evaluation with appropriate surgical intervention if abnormalities are detected are useful for improving subsequent infertility treatment outcomes.
