Systemic Lupus Erythematosus and Mortality in Elderly Patients With Early Breast Cancer.
Article in Arthritis care & research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectivePatients with cancer and systemic lupus erythematosus (SLE) may have worse outcomes than those without SLE, given their comorbidities. We examined survival in elderly women with breast cancer (BC) and SLE and hypothesized that survival would be decreased compared with women with BC but without SLE.
methodsWe identified patients with BC and SLE and patients with BC without SLE in the Texas Cancer Registry and Surveillance, Epidemiology, and End Results, linked to Medicare claims. Overall survival (OS) was estimated after matching (age and cancer stage) and in multivariable Cox proportional hazards models adjusting for other cancer characteristics, treatment, and comorbidities. Two additional cohorts of women without cancer with and without SLE were also studied.
resultsWe identified 494 BC SLE cases and 145,517 BC non-SLE cases, of whom we matched 9,708. Women with SLE were less likely to receive radiation, breast conserving surgery, or endocrine therapy. The 8-year OS estimate for women with early BC (stages 0-II) with and without SLE was 52% (95% confidence interval [95% CI] 45%-59%) and 74% (95% CI 73%-75%), respectively. In the Cox multivariable model, BC and SLE had increased risk of death (hazard ratio [HR] 1.65, 95% CI 1.38-1.98). Women with BC and SLE also had increased risk of death compared with women with SLE but without cancer (HR 1.42, 95% CI 1.05-1.92) after adjusting for SLE severity. Women with SLE and BC received less glucocorticoids, antimalarials, and immunosuppressants after cancer diagnosis than those without cancer.
conclusionSystemic lupus is a risk factor for increased mortality in women with early BC.
