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

backgroundThe impact of social determinants of health (SDoH) on survival outcomes is unclear in the universal Canadian health care system. We investigated the impact of distance to treatment center and income quintile on survival outcomes in pediatric extracranial solid tumors in Canada.

methodsChildren < 15 years old diagnosed with 7 common solid extracranial tumors from 2001 to 2020 were included using the Cancer in Young People in Canada (CYP-C) data tool. We used logistic regression to examine the association of income quintile and distance on cancer outcomes. We used Cox proportional hazard models to examine associations with time-to-event outcomes (OS) and Fine-Gray competing risk regression (recurrence) adjusting for metastasis, age, region, and tumor location.

resultsThe cohort included 3969 patients. Median age was 3.6 years (IQR: 1.3-8.9); 48.7% were female. Tumor diagnosis: 34% neuroblastoma, 21% Wilms tumor, 13% rhabdomyosarcoma, 11% osteosarcoma, 8% Ewing sarcoma, 7% hepatoblastoma, and 6% germ cell tumors. On multivariable analysis, income quintile and distance did not significantly or consistently impact survival across all tumors. In rhabdomyosarcoma, the second lowest income quintile had inferior survival compared to the highest income quintile (p = 0.0264, HR 1.91, 95% CI 1.08, 3.37). In neuroblastoma, the lowest income quintile had inferior survival compared to the highest (p = 0.0052, HR 1.82, 95% CI 1.20, 2.77). Patients diagnosed with hepatoblastoma living > 500 km from a pediatric treatment facility had inferior OS compared to those within 50 km (p = 0.0065, HR 3.29, 95% CI 1.40, 7.79).

conclusionOverall, distance and income did not show a consistent significant impact on survival outcomes for children with extracranial solid tumors.
