Primary Care Use and Clinical Outcomes in a Prevalent Cohort of Patients Receiving Hemodialysis.
Article in Kidney medicine, 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
Rationale & Objective: Primary care is associated with improved health outcomes, but whether this is true for patients receiving dialysis is unclear. We evaluated the association of primary care use in the previous year and clinical outcomes using a prevalent cohort of patients receiving hemodialysis. Study Design: Retrospective cohort study. Setting & Participants: United States Renal Data System registry of prevalent patients requiring maintenance in-center on January 1, 2019, linked with Medicare claims data. Exposure: Primary care use was defined as ≥ 1 outpatient visit to a provider with the specialty of Family, General, Geriatric, or Internal Medicine in the previous year (January 1, 2018, to December 31, 2018). Outcomes: All-cause mortality, cardiovascular mortality, infectious mortality, index hospitalization, emergency department/urgent care, and subsequent primary care visit. Analytical Approach: Inverse probability of treatment weighting (IPTW) to balance patients with primary care use with those without primary care use. Results: Among 122,496 patients (mean age, 65 years; 55% male; 59% White; 71% with diabetes), 60% had used, and 40% had not used, primary care services in the previous year. Primary care use was associated with lower rates of all-cause mortality (HR, 0.90; 95% CI, 0.88-0.92), cardiovascular mortality (HR, 0.96; 95% CI, 0.93-0.99), and infection mortality (HR, 0.81; 95% CI, 0.75-0.88). Primary care use was also associated with higher rates of first hospitalization (HR, 1.04; 95% CI, 1.02-1.05), first emergency department/urgent care use (HR, 1.06; 95% CI, 1.05-1.08), and subsequent primary care use (HR, 4.30; 95% CI, 4.21-4.39). Limitations: Residual/unmeasured confounding as well as limited generalizability given Medicare Primary Payer enrollment. Conclusions: Primary care use among prevalent patients requiring hemodialysis was associated with lower mortality but slightly higher rates of hospitalization and emergency department/urgent care visits.
