Thiazide-Associated Hyponatremia and Mortality Risk: A Cohort Study.
Article in Kidney medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Rationale & Objective: There are likely over 42 million patients with hypertension taking thiazides in the United States and many more worldwide. Hyponatremia is a common complication of thiazide therapy. It is not currently known if thiazide-associated hyponatremia is also associated with increased mortality. The objective of this study was to determine if outpatients who start thiazide diuretic treatment and develop early hyponatremia are at increased risk of mortality when compared with those who do not develop hyponatremia after starting a thiazide. Study Design: A retrospective cohort study. Setting & Participants: This study used data from the TriNetX federated health research network comprising deidentified electronic medical records of ∼93 million patients from 76 health care organizations located primarily in the United States. The study population was adult patients 40-90 years old, with essential hypertension and who started on a thiazide diuretic between January 1, 2010, and December 31, 2021. The patients were then subdivided into a hyponatremia cohort and a control cohort. 22,057 patients met the inclusion criteria for the hyponatremia cohort, and 234,466 patients met the inclusion criteria for the control cohort. After propensity score matching, 22,052 remained in both cohorts. The primary outcome is one-year mortality. Exposure: The hyponatremia cohort developed early hyponatremia defined as a serum sodium ≤ 135 mmol/L within 6 months after initiation of thiazide versus a control that had a serum sodium 136-144 mmol/L after initiation of thiazide. Outcomes: Primary outcome is mortality. Secondary outcomes include development of sepsis, pneumonia, urinary tract infection, cellulitis, myocardial infarction, stroke, congestive heart failure, ataxia, fall, and hip fracture. Analytical Approach: The design is a retrospective cohort study, propensity score matched. Results: Patients in the hyponatremia cohort had a higher hazard of mortality than patients in control, HR 1.96 (95% CI, 1.72-2.28; Limitations: The study had a retrospective design. Conclusions: Patients who develop early hyponatremia (serum sodium ≤ 135 mmol/L) following initiation of a thiazide diuretic have a higher risk of mortality when compared with those who do not develop hyponatremia after initiation of a thiazide diuretic.
