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

introductionSocioeconomic status (SES) and distance to nearest hospital are known social determinants impacting melanoma survival; however, few studies have investigated the effect in a universal healthcare setting, like Canada. MATERIALS AND

methodsThis retrospective study at The Ottawa Hospital (1999-2023) investigated SES and distance lived from the hospital on overall survival, recurrence time, and stage at presentation in melanoma surgical patients. Income quintiles (InQs) were determined using postal codes linked to 2016 census data, and logistic regressions were conducted for the highest and lowest InQs.

resultsOf 959 patients, 277 were in the highest InQ group (mean age: 64; 57% males) and 114 were in the lowest (mean age: 60; 48% males). Higher InQ was significantly associated with lower odds of stage II-IV disease at presentation (p = 0.004, odds ratio: 0.865, 95% CI 0.784 to 0.954), but not with overall survival, recurrence time, or stage III-IV disease. Distance had no significant impact on outcomes. Female sex was protective against recurrence time (p = 0.020, hazard ratio: 0.705), stage II-IV (p = 0.049, odds ratio: 0.766, 95% CI: 0.587, 0.999), and III-IV (p = 0.009, odds ratio: 0.670, 95% CI: 0.496, 0.904) disease.

conclusionHigher SES reduced stage II-IV risk without affecting survival, stage III-IV risk, or recurrence time. Distance to nearest hospital had no significant effect. Females had longer time to recurrence and lower odds of advanced disease. Future research should explore potential educational and primary care barriers that may contribute to advanced stages in lower InQ populations.
