Hereditary brain tumor with a homozygous germline mutation in PMS2: pedigree analysis and prenatal screening in a family with constitutional mismatch repair deficiency (CMMRD) syndrome.
Article in Familial cancer, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
Precise genetic counseling and prenatal diagnosis are often hindered by incomplete penetrance of risk variance and complex patterns of inheritance. Here, we performed a clinical and genetic study of a five-generation Pakistani family with a history of multiple cases of childhood brain tumors. Six affected individuals died of brain tumors at very early ages and three were confirmed as having a homozygous mutation in exon 6 of the PMS2 gene (c.543delT). Fifteen members of the family were identified as heterozygous carriers of this mutation with a lack of cancer incidence. Both clinical manifestations and genetic test results of brain tumor patients in the family support the diagnosis of constitutional mismatch repair deficiency (CMMRD) syndrome, a condition in which individuals carry homozygous germline mutations in mismatch repair machinery genes with an early onset of malignancies such as glioma. This information was used to guide prenatal diagnosis with genetic testing on chorionic villus samples for the family. This is the first report of prenatal genetic diagnosis of hereditary brain tumor.
