Predictive factors associated with health-related quality of life in patients with colorectal cancer in Iran: a cross-sectional study.

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
objectivesThis study aims to identify the primary factors influencing health-related quality of life (HRQoL) in patients with colorectal cancer (CRC), hypothesising that specific patient characteristics and clinical factors significantly impact HRQoL.
designThis was a cross-sectional study conducted over 1 month, from 1 April 2022 to 1 May 2022.
settingThe study was conducted in five hospitals in the northwest region of Iran, focusing on outpatient chemotherapy services.
participantsA total of 251 patients diagnosed with colon and rectal cancer participated in the study. Inclusion criteria included a confirmed diagnosis by an oncologist, ability to communicate, willingness to participate and being aware of their diagnosis and treatment. Exclusion criteria were the presence of other chronic diseases, cognitive disorders, known mental disorders and unwillingness to participate.
interventionsNo interventions were applied as this was an observational study. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the HRQoL of patients with CRC, measured using a standardised SF-36 (36-Item Short Form Health Survey) questionnaire. Secondary outcomes included the impact of demographic and clinical factors on HRQoL.
resultsThe total score of HRQoL in these patients is 47.22±16.78, which indicates that HRQoL is disturbed in these patients. Also, the results of the stepwise multiple regression revealed that among all the participants' characteristics considered, seven factors: not having another disease besides cancer (p<0.001, β: 12.91, 95% CI 8.40, 17.42), only receiving chemotherapy (p<0.001, β: 9.10, 95% CI 4.12, 14.09), not having colostomy (p<0.001, β: 10.27, 95% Cl 5.70, 14.84), female sex (p=0.046, β: -4.52, 95% Cl -8.95, -0.08), living in their own house (p=0.001, β: 11.25, 95% Cl 4.77, 17.73), living in city (p=0.002, 17.74, 95% Cl 6.51, 28.96) and finally not having a job (p=0.003, β: -7.47, 95% Cl -12.31, -2.63), including are the factors that have the most predictive power in HRQoL.
conclusionsThe findings of this study encourage health service providers and planners to pay special attention to the characteristics of patients with CRC as identified in this study. Notably, several HRQoL scores in patients with CRC are low, and the study found that patient characteristics, such as the presence of colostomy, unemployment, female gender and comorbidities, significantly predict the overall HRQoL score. Future research should focus on interventional studies aimed at minimising the adverse effects of disease symptoms on HRQoL in these vulnerable patients.
