Clinical profile and post-transplant anaemia in renal transplant recipients restarting dialysis after a failed graft: changing trends between 2001 and 2009.
Article in Clinical kidney journal, 2013. 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
backgroundThe aim of this study was to compare the clinical profile, outcome and the prevalence and management of anaemia between two cohorts of renal transplant patients with graft failure restarting dialysis in 2001 and 2009.
methodsCross-sectional, observational, retrospective and multicentre study of 397 patients in the 2001 cohort and 222 in the 2009 cohort. Data were recorded at 0, 3, 6, 9 and 12 months before the onset of dialysis resumption and during the first 90 days after restarting dialysis (mortality and hospital admission).
resultsPatients in the 2009 cohort were older at the time of inclusion in the study and transplantation, and restarted dialysis therapy with a significantly better glomerular filtration rate. In both cohorts, there was a rapid deterioration of renal function with statistically significant differences in serum creatinine and glomerular filtration rate between the monthly intervals -12 and 0. The mean haemoglobin value at -12 months was 11.6 g/dL [7.2 mmol/L] in the 2001 cohort when compared with 12.3 g/dL [7.6 mmol/L] in the 2009 cohort, and at the time of restarting dialysis 9.6 g/dL [6.0 mmol/L] versus 10.6 g/dL [6.6 mmol/L]. The percentage of patients treated with erythropoiesis-stimulating agents, at any time during the 12 months before readmission to dialysis, increased significantly from 61.5% in the 2001 cohort to 96% in the 2009 cohort. There were no significant differences between the 2001 and 2009 cohorts in mortality rate (8.8 versus 9.0%) or hospital admission (31.5 versus 31.1%) during the study time.
conclusionsAt restarting dialysis, the proportion of patients with anaemia (and its severity) due to progressive graft nephropathy decreased over the past 8 years, increasing significantly the percentage of patients treated with erythropoietin. Differences in morbimortality after dialysis resumption were not observed, this is probably due to an increase in the age of donors and recipients.
