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: Lithopedion is an exceptionally rare complication of abdominal pregnancy in which a deceased fetus becomes calcified following prolonged retention in the maternal abdomen. Because of its indolent course and nonspecific symptoms, it is frequently diagnosed late, particularly in resource-limited settings. Case Presentation: We report a 42-year-old multiparous woman (gravida 4, para 3) who presented with a three-year history of chronic lower abdominal pain and progressive abdominal heaviness. She had a remote history suggestive of an untreated pregnancy that spontaneously ceased without medical evaluation. Clinical examination revealed a firm, irregular, non-mobile abdominopelvic mass extending to the umbilical level. Laboratory investigations revealed mild anemia (hemoglobin 9.0 g/dL), while serum β-hCG was <5 mIU/mL (negative). Ultrasonography demonstrated a calcified abdominopelvic mass with an empty uterine cavity. Contrast-enhanced computed tomography with three-dimensional reconstruction demonstrated a well-defined calcified extrauterine fetal skeleton consistent with lithopedion. Intraoperative findings met Studdiford's criteria; however, because these criteria were applied retrospectively several years after the index pregnancy, the underlying gestation is described as a presumed primary abdominal pregnancy. Management and Outcome: The patient underwent exploratory laparotomy with complete surgical excision of the calcified fetus without intraoperative complications. Postoperative recovery was uneventful, and the patient demonstrated complete resolution of symptoms at follow-up. Conclusion: Lithopedion should be considered in women presenting with chronic abdominal or pelvic symptoms and a history suggestive of prior untreated pregnancy. In this patient, cross-sectional imaging, and particularly CT with three-dimensional reconstruction, was valuable for characterizing the lesion and planning surgery, although ultrasonography and magnetic resonance imaging may be sufficient in other circumstances. Surgical management in symptomatic cases can result in excellent outcomes even in resource-limited settings.
