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
backgroundMultimorbidity among Hispanic patients with colorectal cancer in Puerto Rico remains poorly understood despite their potential impact on patient outcomes. We examined patterns of chronic conditions at colorectal cancer diagnosis and their associations with sociodemographic factors, stage at diagnosis, and tumor location.
methodsWe used the Puerto Rico Central Cancer Registry-Health Insurance Linkage Database (2012-2020). Adults ≥50 years of age with a first colorectal cancer diagnosis were included. Chronic conditions were identified using Medicare and Medicaid Chronic Conditions Data Warehouse algorithms. Latent class analysis and regression models assessed multimorbidity patterns and associations with sociodemographic and tumor characteristics.
resultsAmong 6,543 adults with colorectal cancer (mean age, 67.7 years; 45.7% female), 52.7% had no additional chronic conditions, 18.7% had 1, and 28.6% had ≥2 conditions. The most prevalent comorbidities were hypertension (20.6%), diabetes (14.4%), and hyperlipidemia (12.2%). Three multimorbidity patterns were identified: hypertensive-vision-joint, diabetic renal, and cardiopulmonary severe. Advanced age, female sex, and Medicare insurance predicted class membership. Older age was associated with membership in the cardiopulmonary severe group [adjusted prevalence ratio (aPR) = 1.75 for ages 76-85 years; aPR = 2.86 for ≥86 years]. Females were more likely to belong to the hypertensive-vision-joint group (aPR = 1.42). Multimorbidity patterns were not associated with tumor location or stage at diagnosis.
conclusionsMultimorbidity is common among older Hispanic adults with colorectal cancer in Puerto Rico and forms distinct patterns associated with sociodemographic factors, highlighting heterogeneity in medical complexity. IMPACT: Identifying multimorbidity patterns among older patients with colorectal cancer in Puerto Rico underscores the need for integrated, patient-centered care for aging Hispanics.
