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
backgroundApproximately 50% of early spontaneous abortions are found to have chromosomal abnormalities. In these cases, certain histopathologic abnormalities are suggestive of, although not diagnostic for, the presence of chromosomal abnormalities. However, placental histomorphology in cases of complex chromosomal abnormalities, including double trisomies, is virtually unknown. CASE REPORT: We present the case of a 27-year-old G3P22002 female presenting at 19 weeks and 1 day of gestation by last menstrual period for scheduled prenatal visit. Ultrasound revealed a single fetus without heart tones and adequate amniotic fluid. Limited fetal measurements were consistent with estimated gestational age of 17 weeks. Labor was induced with misoprostol due to fetal demise. Autopsy revealed an immature female fetus with grade 1-2 maceration. The ears were low-set and posteriorly rotated. The fingers were short bilaterally, and the right foot showed absence of the second and third digits. Evaluation of the organs showed predominantly marked autolysis consistent with retained stillbirth. Placental examination revealed multiple findings, including focal pseudovillous papilliform trophoblastic proliferation of the undersurface of the chorionic plate and clustering of perpendicularly oriented sclerotic chorionic villi in the chorion laeve, which have not been previously reported in cases of chromosomal abnormalities. Karyotype of placental tissue revealed a 48,XXX,+18 karyotype and the same double trisomy of fetal thymic tissue by FISH.
conclusionIn addition to convoluted outlines of chorionic villi, villous trophoblastic pseudoinclusions, and clusters of villous cytotrophoblasts, the previously unreported focal pseudovillous papilliform trophoblastic proliferation of the undersurface of the chorionic plate and clustering of perpendicularly oriented sclerotic chorionic villi in the chorion laeve were observed in this double trisomy case. More cases have to be examined to show if the histology is specific for this double trisomy.
