Temporal evolution of C-reactive protein levels and its association with the incident hospitalization risk among individuals with stage 3-4 chronic kidney disease.

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
backgroundElevated C-reactive protein (CRP) levels as an inflammatory marker have been associated with poor outcomes in patients with chronic kidney disease (CKD). However, its single assessment may not reflect clinical significance before an adverse clinical endpoint. We studied the CRP level trajectories, which may be related with the intensity of the inflammatory process, and its association with time-to-first hospitalization in CKD.
methodsA cohort of 739 patients with stage 3-4 CKD were retrospectively observed for seven years. The time-to-event outcome was all-cause hospitalization. Clinical and laboratory features were measured at baseline. Longitudinal changes in naturally logged CRP levels were modeled using the Joint Longitudinal-Survival model adjusted with baseline covariates.
resultsLogged CRP changes were evaluated with a median measurement (interquartile range) of 4 (2, 7), during a median (interquartile range) follow-up of 2.3 (1.2, 3.9) years. The estimated mean increase in logged CRP was 0.35 mg/L per year. 299 (40.5%) patients reached the endpoint, and increase in logged CRP with time was associated with increased risk of hospitalization (HR 1.96; 95% CI 1.05-3.66; p = 0.034), but baseline logged CRP did not have a significant effect on the time-to-first hospitalization (HR 0.98; 95% CI 0.85-1.13; p = 0.736).
conclusionAll-cause hospitalization was associated significantly with CRP trajectories. Temporal evolutions of these repeatedly measured biomarkers might predict clinical outcomes in patients with CKD and may be useful for individual risk profiling. Furthermore, early management may provide an opportunity to better patient survival.
