Hereditary Cancer Screening and Outcomes at an Urban Safety-Net Hospital.
Article in JCO precision oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposePatients with hereditary cancer syndromes (HCS) have a high lifetime risk of developing cancer. Historically underserved populations have lower rates of genetic evaluation. We sought to characterize demographic factors that are associated with undergoing HCS evaluation in an urban safety-net patient population.
methodsAll patients who met inclusion criteria for this study from 2016 to 2021 at an urban safety-net hospital were included in this analysis. Inclusion criteria were pathologically confirmed breast, ovarian/fallopian tube, colon, pancreatic, and prostate cancers. Patients also qualified for hereditary breast and ovarian cancers or Lynch syndrome on the basis of National Comprehensive Cancer Network guidelines. Institutional review board approval was obtained. Demographic and oncologic data were collected through retrospective chart review. Univariable and multivariable logistic regression models were constructed.
resultsOf the 637 patients included, 40% underwent genetic testing. Variables associated with receiving genetic testing on univariable analysis included patients living at the time of data collection, female sex, Latinx ethnicity, Spanish language, family history of cancer, and referral for genetic testing. Patients identifying as Black, having Medicare, having pancreatic or prostate cancer, having stage IV disease, having Eastern Cooperative Oncology Group (ECOG) prognostic score ≥1, having medium or high Charlson comorbidity index, with current or previous cigarette use, and with previous alcohol use were negatively associated with testing. On multivariable modeling, family history of cancer was positively associated with testing. Patients identifying as Black, having colon or prostate cancer, and having ECOG score of 2 had significantly lower association with genetic testing.
conclusionUptake of HCS was lower in patients identifying as Black, those with colon or prostate cancer, and those with an ECOG score of 2. Efforts to increase HCS testing in these patients will be important to advance equitable cancer care.
