Association of long cardiac troponin T forms with adverse long-term outcomes in patients with advanced chronic kidney disease.
Observational study in BMC nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04223726 (Chronic Arterial Disease, Quality of Life and Mortality in Chronic Kidney Injury), which is not on this 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.

Abstract
backgroundCommercial high-sensitivity cardiac troponin T (hs-cTnT) assays measure both intact and degraded cTnT forms (i.e. total cTnT) and values are often elevated in chronic kidney disease (CKD) patients. The measurement of long cTnT forms has recently shown improved specificity for acute myocardial infarction compared to total cTnT. However, the associations between long cTnT and adverse long-term outcomes in CKD are unknown.
methodsAltogether, 136 CKD stage 4-5 patients not on dialysis were included in this prospective cohort study. Long cTnT and total cTnT levels before dialysis initiation were measured using investigational in-house immunoassays. The associations between cTnT measurements and all-cause mortality, incident major adverse cardiovascular or cerebrovascular events (MACCE), new-onset atrial fibrillation (NOAF) and a composite adverse outcome (all-cause mortality or MACCE) were assessed.
resultsMean age was 61 (±13) years, 47 (34.6%) were female and median values for long cTnT and total cTnT were 1.9 (1.3-3.0) ng/L and 37 (23-66) ng/L, respectively. After a median follow-up of 6.2 (4.6-7.7) years, 62 (45.6%) patients had died, 36 (26.5%) had experienced MACCE, 28 (23.3%) NOAF and 76 (55.9%) a composite adverse outcome. In multivariable Cox models adjusted for age, sex and coronary artery disease (CAD), long cTnT and total cTnT were independently associated with all-cause mortality, NOAF and the composite adverse outcome, while only total cTnT was associated with MACCE. Replacing the adjustment for CAD with kidney transplantation in the multivariable models weakened the significance of the associations.
conclusionsWe describe for the first time associations between long cTnT and long-term cardiovascular adverse outcomes and all-cause mortality in a prospective cohort of CKD stage 4-5 patients.
