Risk scores to predict mortality 2 and 5 years after surgery for colorectal cancer in elderly patients.
Observational study in World journal of surgical oncology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02488161 (Risk Factors of Adverse Outcomes at Short and Medium Term, and Development of Predictive Models, in Patients With Colorectal Cancer. IRYSS-coordinated Multicenter Study), which is not on this map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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.

Abstract
backgroundThe aim of this study was to identify predictors of mortality in elderly patients undergoing colorectal cancer surgery and to develop a risk score.
methodsThis was an observational prospective cohort study. Individuals over 80 years diagnosed with colorectal cancer and treated surgically were recruited in 18 hospitals in the Spanish National Health Service, between June 2010 and December 2012, and were followed up 1, 2, 3, and 5 years after surgery. Sociodemographic and clinical data were collected. The primary outcomes were mortality at 2 and between 2 and 5 years after the index admission.
resultsThe predictors of mortality 2 years after surgery were haemoglobin ≤ 10 g/dl and colon locations (HR 1.02; CI 0.51-2.02), ASA class of IV (HR 3.55; CI 1.91-6.58), residual tumour classification of R2 (HR 7.82; CI 3.11-19.62), TNM stage of III (HR 2.14; CI 1.23-3.72) or IV (HR 3.21; CI 1.47-7), LODDS of more than - 0.53 (HR 3.08; CI 1.62-5.86)) and complications during admission (HR 1.73; CI 1.07-2.80). Between 2 and 5 years of follow-up, the predictors were no tests performed within the first year of follow-up (HR 2.58; CI 1.21-5.46), any complication due to the treatment within the 2 years of follow-up (HR 2.47; CI 1.27-4.81), being between 85 and 89 and not having radiotherapy within the second year of follow-up (HR 1.60; CI 1.01-2.55), no colostomy closure within the 2 years of follow-up (HR 4.93; CI 1.48-16.41), medical complications (HR 1.61; CI 1.06-2.44), tumour recurrence within the 2 years of follow-up period (HR 3.19; CI 1.96-5.18), and readmissions at 1 or 2 years of follow-up after surgery (HR 1.44; CI 0.86-2.41).
conclusionWe have identified variables that, in our sample, predict mortality 2 and between 2 and 5 years after surgery for colorectal cancer older patients. We have also created risks scores, which could support the decision-making process.
