Health-related quality of life in patients with cancer in Lubumbashi/Democratic Republic of the Congo: a semi-structured qualitative and quantitative prospective cross-sectional study.
Article in BMJ open, 2026. 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
objectivesHealth-related quality of life (HRQoL) assessments are a cornerstone of outcome evaluations for patients with cancer. The aim of this project was to assess patients with cancer in Lubumbashi/Democratic Republic of the Congo and: (1) evaluate what constitutes a clinically important health problem, (2) evaluate HRQoL and (3) compare HRQoL to controls.
designCross-sectional, prospective study.
settingPatient recruitment took place in 12 hospitals in Lubumbashi.
participantsInclusion criteria were a secured diagnosis of cancer, aged 18 years and above, no serious cognitive impairments. PRIMARY AND SECONDARY OUTCOME MEASURES: (1) Semi-structured interviews with patients and healthcare professionals were conducted to investigate aspects of clinical importance. (2) The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) was employed to quantitatively assess HRQoL; (3) an exploratory comparison of HRQoL data to Spanish controls, multinational reference data and the European general population data is performed.
results(1) 20 patients (x̄-age=55.0 years; 70.0% female) and 10 healthcare professionals were interviewed. Social isolation, need for help/care and worries were frequently mentioned aspects making a health problem clinically important. (2) 103 patients (x̄-age=54.0 years; 67.0% female) with various cancer types were assessed. The prevalence of clinically important problems ranged from 26.2 % for fatigue to 94.1% for financial problems. (3) Compared to matched Spanish controls (n=207), symptom burden was more pervasive (OR 1.18 for insomnia to 28.0 for financial problems) than functional health limitations (max. OR 2.12 for role function). While adjusting HRQoL scores for age, sex, comorbidities and treatment intention decreased effect sizes of score difference across countries for 14 out of 16 scales, statistically significant differences across countries (p<0.05) remained for ten scales even after adjusting for covariates.
conclusionClinical characteristics, aspects of clinical importance and HRQoL profiles of patients with cancer in Lubumbashi were reported. Aspects of clinical importance were identified, whereas a high symptom burden was reported by patients with cancer in Lubumbashi. Enhancing symptom management in Lubumbashi may alleviate symptom burden of patients with cancer.
