Long-term Survival and Prognostic Factors of Breast Cancer.
Article in Archives of Iranian medicine, 2022. 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
backgroundBreast cancer survival rate is an important index for assessment of treatment effect in reducing the mortality. Weaimed to determine the fifteen-year survival rate for breast cancer at a referral center in Iran and its correlated factors.
methodsThis survival study enrolled patients with breast cancer who referred to Motamed Cancer Institute (MCI) from 1998 to2016. The survival rate was calculated using the Kaplan-Meier method. The relationship of demographic, clinical and therapeuticfactors with overall survival (OS) was studied using Cox's proportional hazard model.
resultsTotally, 3443 patients were studied. Their mean age and follow-up period were 47.7 (±11.43) years and 61.66 (±52.1)months, respectively. The median follow-up time was 48.4 months (range: 1-413 months), 49.7% of the patients had high schoolor higher education, and 71.3% presented in the early stage of the disease. Death occurred in 505 (14.7%) of the patients. Theoverall 2-, 5-, 7-, 10- and 15-year survival rates were 93%, 82%, 78%, 74%, and 66%, respectively. Lymph node involvement(HR=2.07; 95% CI: 1.38-3.09), tumor size≥5 cm (HR=2.83; 95% CI: 1.59-2.04), being single/divorced/widowed (HR=1.65;95% CI: 1.13-2.4), and education level<high school diploma (HR=1.57; 95% CI: 1.13-2.17) were independent predictors ofbreast cancer survival.
conclusionThe five-year breast cancer survival rate in this study was higher than reported by some other studies in Iran, whichcould be due to the multidisciplinary treatment approach in MCI. Tumor size and lymph node involvement as indicators ofdelayed diagnosis may affect breast cancer survival, even though their true effect due to lead-time bias should be considered. Thecorrelation of education level with survival confirms the importance of awareness and the need to establish strategies for earlydiagnosis in Iranian women.
