Prognostic value of E2F1 in rectal cancer.
Article in Turkish journal of surgery, 2017. 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
objectiveTo evaluate whether E2F transcription factor 1 is a potential prognostic marker in patients with rectal cancer. MATERIAL AND
methodsEighty-two patients who were treated with curative resection because of rectal cancer in the Erciyes University School of Medicine, Department of General Surgery were included in the study and analyzed retrospectively. Data were obtained from patient files, pathology reports, and hospital information system. Nuclear and cytoplasmic staining of E2F transcription factor 1 was performed for immunohistochemical analysis on paraffin-embedded and blocked tumor tissue samples of patients. The findings of the study were assessed with using IBM Statistical Package for Social Sciences Statistics 20.
resultIn the 5-year follow-up period, 34 (41.5%) patients were alive. Local recurrence was identified in 7 patients. According to E2F transcription factor 1 nuclear staining, the average survival rate in patients was 60% for strong nuclear staining and 28% for weak nuclear staining. There was significant statistical difference between groups according to their degree of nuclear staining (p=0.017). When the patients were evaluated according to cytoplasmic staining with E2F transcription factor 1, the average overall survival rate of patients with positive E2F transcription factor 1 cytoplasmic staining was 48.0±4.6% versus 55.9±7.9% for patients without staining (p=0.408).
conclusionThe survival rates are higher in rectal cancer patients with strong immunohistochemical nuclear staining of E2F transcription factor 1.
