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

objectiveThe aim of the present study was to asses the accuracy of prediction equations in elderly patients with advanced renal disease (ARD). PATIENTS AND

methodsTwenty-three elderly patients (>60 years) with chronic kidney disease (CKD) stages 3-5 underwent technetium-99 m-diethylenetriaminepentaacetic acid (Tc-99m-DTPA) radionuclide measurement of glomerular filtration rate (GFR). To predict GFR, estimation formulas [Cockcroft-Gault (CG), 6-variable Modification of Diet in Renal Disease (6-var-MDRD) and the corrected 24-hour creatinine clearance (24-h CCL) method] were used. Estimates of bias and precision were obtained to compare prediction equations of GFR with standard radionuclide measurement.

resultsIn the present study, all the prediction equations overestimated the GFR measured with the radionuclide method. Six-var-MDRD and 24-h CCL methods correlated better with standard radionuclide measurements compared to the CG formula (Rc of 0.53 and 0.50 vs. 0.41, respectively) as for GFR prediction, but they were still insufficiently accurate.

conclusionGlomerular filtration rate prediction equations correlate poorly with standard radionuclide measurements and their use may lead to late initialization of renal replacement therapy in elderly patients with ARD. Therefore, measurement by standard radionuclide method (Tc-99m-DTPA) is recommended to accurately assess GFR in elderly patients with ARD.
