Pre-transplant parathyroid hormone serum levels as predictors of kidney function after one year: a retrospective cohort study.

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
objectiveThis study aimed to evaluate the association between pre-transplant parathyroid hormone levels and renal function 1-year after kidney transplantation.
methodsThis retrospective cohort study was conducted at a tertiary public university hospital and included all patients who underwent kidney transplantation between May 2012 and September 2020. Patients under 18 years of age and those who received a transplant from a living donor were excluded. The primary outcome was renal function at 1 year, as assessed using the CKD-EPI formula. Univariate and multivariate analyses were performed to identify predictors of graft function at one year clinical and laboratory variables.
resultsDuring the study period, 1,128 kidney transplants were performed. After applying exclusion criteria, 382 patients from six dialysis centers were included in the final analysis. Pre-transplant parathyroid hormone levels were not associated with renal function in either univariate or multivariate analyses (p=0.968 and p=0.616, respectively). In the multivariate analysis, recipient age (Coefficient: -0.41, 95% CI= -0.63 to -0.20, p<0.001) and Kidney Donor Profile Index (Coefficient: -0.44, 95%CI= -0.54 to -0.33, p<0.001) were significantly associated with graft function at 1 year.
conclusionPre-transplant serum levels of intact parathyroid hormone levels were not associated with renal function 1 year after transplantation. Conversely, recipient age and Kidney Donor Profile Index showed significant associations with graft outcomes, highlighting the importance of individualized risk assessment in transplant evaluation.
