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
aimPalliative rectal cancer patients typically retain their primary tumour, as trials have concluded no survival benefit of tumour resection in non-curative patients. This patient group is understudied regarding the natural course of the remaining tumour, particularly concerning the need of surgical management.
methodThis was a retrospective study on rectal cancer patients diagnosed between 2007 and 2020 in Region Västerbotten, Sweden. Data were obtained from the Swedish Colorectal Cancer Registry and chart review. Patients were excluded if treated with curative intent, underwent primary tumour resection, had a synchronous colorectal cancer, had locally recurrent colorectal cancer, or refused treatment. Patients were followed from diagnosis until death or end of follow-up. Indications for palliative treatment, tumour-related complications and surgical and oncological management were investigated, with a stratified analysis for study period and patient age.
resultsSome 156 patients remained after applying exclusion criteria. The majority had metastasized and incurable disease (76%). Almost half suffered local complications (44%) and 48% underwent surgical intervention, due to the unremoved primary tumour. Tumour perforation occurred in 7% with a significantly higher risk in patients aged ≤75 years (p = 0.009). Bowel obstruction afflicted 23%, while 40% underwent stoma diversion. Almost half received chemotherapy (48%) and radiotherapy (42%), respectively.
conclusionRectal cancer patients with an unremoved primary tumour face a substantial risk of local complications, often necessitating surgical intervention. Therefore, the benefits of surgical resection should be carefully considered, especially for patients with a longer estimated survival. Further research is needed to accurately identify patients where tumour removal might be beneficial.
