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
purposeIt is known that vitamin D has positive effects on graft functions (reduce fibrosis, suppress excessive inflammatory response, improve graft functions). In our study, it was aimed to evaluate the effects and predictive roles of vitamin D, the expression of vitamin D receptor (VDR) in lymphocytes, monocytes, natural killer cells on chronic rejection and graft functions in kidney transplant patients.
methodsSeventy one people were included in the study and analyses were made by dividing them into 3 groups. Group 1: Healthy control (n = 29), Group 2: Kidney transplant patients with stable kidney function (n = 17), and Group 3: Kidney transplant patients with chronic rejection diagnosis (n = 25). Serum 25-hydroxycholecalciferol, 1.25 dihydroxycholecalciferol levels and VDR percentages in CD4 + , CD8 + , CD14 + , CD56 + cells were measured in 3 groups. ROC analyses and logistic regression models were performed to predict rejection and long-term graft functions.
resultsThe percentage of VDR expression in CD4 + lymphocytes (p < 0.001) and CD14( +) monocytes (p < 0.001), 25-hydroxycholecalciferol and 1.25 dihydroxycholecalciferol levels were lower in group 3 was detected. In ROC analyses and logistic regression models, VDR expression in CD4( +)T lymphocytes was shown to have a statistically significant value in the development of chronic rejection (Odds ratio 0.86: 0.76-0.92; p = 0.001/AUC = 0.941, p < 0.001) and prediction of 5th-year graft functions (Odds ratio 0.93: 0.88-0.98; p = 0.017/AUC = 0.745, p = 0.007).
conclusionIn our study, it was shown that low vitamin D and VDR expression is associated with poor outcome and VDR expression in CD4( +)T lymphocytes is predictive in terms of graft function and rejection.
