Impact of steroid maintenance on the outcomes in first-time deceased donor kidney transplant recipients: Analysis by induction type.
Article in World journal of transplantation, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimTo analyze the impact of steroid maintenance on the outcomes in kidney transplant recipients stratified by induction agent received.
methodsPatients who underwent first-time deceased donor kidney transplantation between 2000 and 2008 after receiving induction therapy with rabbit-antithymocyte globulin (r-ATG), alemtuzumab or an interleukin-2 receptor blocker (IL-2B) and discharged on a calcineurin inhibitor (CNI)/mycophenolate mofetil (MMF)-regimen along with or without steroids were identified from the Organ Procurement and Transplant Network/United Network of Organ Sharing database. For each induction type, adjusted overall and death-censored graft as well as patient survivals were compared between patients discharged on steroid vs no steroid. Among r-ATG induced patients, analysis was repeated after splitting the group into low and high immune risk groups.
resultsAmong the 37217 patients included in the analysis, 17863 received r-ATG (steroid = 13001, no-steroid = 4862), 3028 alemtuzumab (steroid = 852, no-steroid = 2176) and 16326 IL-2B (steroid = 15008, no-steroid = 1318). Adjusted overall graft survival was inferior (HR = 1.16, 95%CI: 1.06-1.27, P = 0.002) with similar death-censored graft survival (HR = 0.99, 95%CI: 0.86-1.14, P = 0.86) for steroid vs no-steroid groups in r-ATG induced patients. Both adjusted overall and death-censored graft survivals for steroid vs no-steroid groups were similar in alemtuzumab (HR = 0.92, 95%CI: 0.73-1.15, P = 0.47 and HR = 0.87, 95%CI: 0.62-1.22, P = 0.43 respectively) and IL-2B (HR = 1.05, 95%CI: 0.91-1.21, P = 0.48 and HR = 0.94, 95%CI: 0.75-1.18, P = 0.60 respectively) induced groups. Adjusted patient survivals were inferior for steroid vs no-steroid groups in r-ATG induced (HR = 1.31, 95%CI: 1.15-1.49, P < 0.001) but similar in alemtuzumab (HR = 1.02, 95%CI: 0.75-1.38, P = 0.92) and IL-2B (HR = 1.17, 95%CI: 0.97-1.40, P = 0.10) induced patients. Among the r-ATG induced group there were 4346 patients in the low immune risk and 13517 patients in the high immune risk group. Adjusted overall graft survivals were inferior for steroid vs no steroid groups in both low immune (HR = 1.34, 95%CI: 1.09-1.64, P = 0.001) and high immune (HR = 1.18, 95%CI: 1.07-1.30, P = 0.005) risk groups. Adjusted death-censored graft survivals for steroid vs no steroid groups were similar in both low (HR = 1.06, 95%CI: 0.78-1.45, P = 0.70) and high (HR = 1.04, 95%CI: 0.98-1.20, P = 0.60) immune risk groups. Adjusted patient survivals were inferior for steroid vs no steroid groups in both low immune (HR = 1.54, 95%CI: 1.18-2.02, P < 0.001) and high immune (HR = 1.32, 95%CI: 1.16-1.51, P = 0.002) risk groups. Overall, there were significantly higher deaths from infections and cardiovascular causes in patients maintained on steroids.
conclusionOur study showed an association between steroid addition to a CNI/MMF-maintenance regimen and increased death with functioning graft in patients receiving r-ATG induction for first-time deceased donor kidney transplantation.
