1 · What the graph read from it

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.

2 · The registry

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

backgroundSteroids are widely used in maintenance immunosuppression treatment in kidney transplant recipients. Older individuals undergo age-related immunosenescence that consequently decreases their ability to process and evoke a response to foreign antigens. Thus, steroids may not be necessary in preventing allograft rejection and may consequently increase older recipients' risk of long-term steroid-related adverse effects.

objectiveThe objective of this study was to analyze the adverse outcomes of long-term steroid immunosuppression in older kidney transplant recipients using real-world electronic medical record data.

methodsThe TriNetX database "US Collaborative Network" was utilized to perform a propensity score-matched case-control study comparing 1-year, 3-year, and 5-year adverse effects of steroid immunosuppression in older adults (aged ≥ 65 years) kidney transplant recipients who underwent either an early-steroid withdrawal (ESW) maintenance regimen or a steroid continuous immunosuppression (SCI) regimen between 31 December, 2010 and 31 December, 2020. Early-steroid withdrawal was defined as tacrolimus plus mycophenolate mofetil maintenance with no prednisone after the seventh day post-transplant. Steroid continuous immunosuppression was defined as tacrolimus plus mycophenolate mofetil plus prednisone maintenance. Cohorts were matched on age, race/ethnicity, and risk factors for adverse steroid-related outcomes and rejection. Outcomes included post-transplant diabetes mellitus, dyslipidemia osteoporosis/fractures, myocardial infarction, glaucoma/cataract, stroke, pulmonary embolism, and malignancy. Secondary outcomes analyzed incidences of infection-related outcomes, graft-related outcomes, and recipient mortality.

resultsAfter matching, there were 304 recipients in each group (ESW, SCI). Mean age at the time of transplant was 69.2 ± 3.7 years (ESW) and 69.2 ± 3.4 years (SCI, p = 0.96). The Kaplan-Meier analysis showed recipients who underwent SCI had increased incidences of post-transplant diabetes mellitus at 1 year (22.36% vs 30.37%, p = 0.01) and 3 years (34.89% vs 44.29%, p = 0.01), but this became non-significant at 5 years post-transplant (41.97% vs 42.6%, p = 0.34). Incidences of acute pancreatitis were higher for the SCI cohort at 3 years (p = 0.02) as well as incidences of acute myocardial infarction at 5 years post-kidney transplant (6.75% vs 14.39%, p < 0.01). No difference was found for other adverse outcomes. Early-steroid withdrawal recipients experienced significantly fewer infection-related outcomes, such as cytomegalovirus, BK virus, sepsis/bacteremia, and fungal infections, compared with SCI recipients. Last, recipients who underwent ESW experienced fewer incidences of rejection and death-censored graft failure at 5 years post-transplant.

conclusionsThere is currently no standard maintenance immunosuppression protocol for older kidney transplant recipients. Death-censored graft survival, rejection, and patient survival were improved with ESW. Steroid minimization may be beneficial in this population given that it lowers the risk of drug-induced adverse effects.
