Serum creatinine concentration and creatinine-based estimation of glomerular filtration rate in athletes.
Review in Sports medicine (Auckland, N.Z.), 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers.
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
Since serum creatinine concentration test results in athletes can sometimes be abnormal, correct test interpretation needs to take account of the sportsman's status, as well as the transient exercise-induced changes in creatinine and the marked differences in creatinine levels among athletes competing in different sport disciplines. Serum creatinine concentration in athletes is related to body mass index, so the use of general population reference ranges should not be recommended in sports medicine. This does not necessarily imply, however, that specific creatinine reference ranges for athletes need to be defined. The individuality index (the ratio between intra- and interindividual variability) for creatinine is about half (0.33 vs 0.60) the generally considered lower limit for a population-based reference interval to be classified as useful. Prediction of glomerular filtration rate in athletes by means of creatinine-based equations is also questionable because of discrepancies among formulae, owing to the particular anthropometric characteristics of athletes (high body mass index). Furthermore, differences in muscle mass need to be entered into the recommended equations for calculating the estimated glomerular filtration rate (eGFR) in athletes. Based on current knowledge about creatinine measurement and eGFR calculation, we suggest that athletes be monitored periodically by consecutive creatinine level assessments, comparing the values reported during the training and competition season with the baseline levels recorded during the recovery period.
