Can Pre-Transplant Psychometric Testing Predict Tacrolimus Intrapatient Variability After Living Kidney Transplantation?
Article in Psychiatry investigation, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
objectiveTacrolimus intrapatient variability (Tac IPV) has been considered a marker for post-graft risk. We investigated pre-transplant psychometric testing to predict Tac IPV after living kidney transplantation.
methodsMinnesota Multiphasic Personality Inventory-2 (MMPI-2) examined during pre-transplant evaluation by 102 recipients were analyzed. Subjects were divided into two groups, low IPV (L-IPV) and high IPV (H-IPV), by cutoffs of Tac IPV: median of 24 and value of 30. T-scores of MMPI-2 scales were used to analyze difference between L-IPV and H-IPV using independent t-tests. Stepwise multiple logistic regression was used to test whether MMPI-2 scales affected Tac IPV. Confusion matrix of logistic regression was used to explain statistical power. Cutoff values of significant scales for H-IPV were analyzed by constructing receiver operating characteristic curves.
resultsHysteria (Hy) and depression (D) scale scores and Tac IPV were associated in IPV 24 (odds ratio [OR]: 1.08, p<0.01 for Hy; OR: 0.93, p<0.01 for D) and IPV 30 models (OR: 1.09, p<0.01 for Hy; OR: 0.92, p<0.01 for D). Paranoia (Pa) scale scores were associated with Tac IPV in IPV 24 model (OR=1.10, p<0.01) and were significantly higher in H-IPV 24 (p<0.01). F1 scores of confusion matrix in IPV 24 and 30 models were 0.70 and 0.71, respectively. Cutoffs of Hy, D, and Pa scales were 51, 57, and 47, respectively.
conclusionMMPI-2 profile is suggested as a predictor for high Tac IPV after living kidney transplantation.
