High dose chemoradiotherapy increases chance of organ preservation with satisfactory functional outcome for rectal cancer.
Article in Radiation oncology (London, England), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundHigh dose chemoradiotherapy offers a curative chance for patients with rectal cancer that are unfit or unwilling to undergo surgical resection, yet its long-term survival and functional outcomes have been rarely investigated.
methodsPatients with non-metastatic rectal adenocarcinoma who received pelvic radiation for curative intent from April 2006 to July 2017 were retrospectively investigated. Survival rates were analyzed using the Kaplan-Meier method. Quality of life and functional outcomes were evaluated using the EORTC quality of life questionnaire.
resultsA total of 57 patients were included, with a median age of 59.0 (range, 29-84) years. The numbers of patients who were diagnosed as stage I, II and III were 5 (8.8%), 16 (28.1%) and 36 (63.2%), respectively. 53 (93.0%) patients had tumor located within 5 cm from the anal verge. All patients received fluorouracil-based concurrent chemoradiotherapy with a median radiation dose of 80 (range, 60-86) Gy. All kinds of grade 3-4 adverse events occurred in 18 (31.6%) patients. 42 (73.7%) patients achieved a clinical complete response after chemoradiotherapy. After a median follow-up of 43.5 (range 14.9-163.2) months, 12 (21.1%) patients had local progression and 11 (19.3%) developed distant metastasis. The 3-year local recurrence-free survival and distant metastasis-free survival were 77.3% (95% CI, 65.7-88.8%) and 79.2% (95% CI, 68.2-90.2%), while the 3-year progression-free survival, cancer-specific survival, overall survival were 61.9% (95% CI, 48.8-75.0%), 93.1% (95% CI, 85.8-100.0%) and 91.4% (95% CI, 83.6-99.2%), respectively. For patients who had tumor located within 3 cm from the anal verge, the sphincter preservation rate was 85.3% at last follow-up. Long-term adverse events mainly were anal blood loss. 21 patients completed the quality-of-life questionnaire and had a score of the global health status of 78.57 ± 17.59. Of them, 95.2% reported no urinary incontinence and 85.7% reported no fecal incontinence.
conclusionsHigh dose chemoradiation demonstrated promising survival outcomes with acceptable short-term and long-term side effects, and satisfying long-term functional outcomes and quality of life. It could be considered as a non-invasive alternative for rectal cancer patients who refuse surgery.
