Reference values for renal size obtained from MAG3 scintigraphy.
Article in Clinical nuclear medicine, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeThe purposes of this study were to establish reference values for renal size determined from 99mTc-MAG3 renal scintigraphy and to derive regression equations to predict normal limits.
methodsThe study population consisted of 106 subjects evaluated for kidney donation who underwent 99mTc-MAG3 renal scintigraphy. Renal length, width, and area were determined from the pixel length and area of whole-kidney regions of interest and correlated with patient sex, height, weight, body mass index, and body surface area (BSA). Reference values were obtained based on estimation of the lower and upper percentiles via quantile regression.
resultsThe mean (SD) left and right kidney lengths was 12.2 (1.0) and 12.1 (1.0) in male and 11.9 (0.9) and 11.8 (0.9) in female patients, respectively. Sex was not a significant factor in the quantile regression models. Regression equations defining the lower and upper limits of renal length (cm) and area (cm) are as follows: left kidney length (5th percentile), 8.2+1.3×BSA; left kidney length (95th percentile), 9.1+2.3×BSA; right kidney length (5th percentile), 8.8+1.0×BSA; right kidney length (95th percentile), 11.1+1.4×BSA; left kidney area (5th percentile), 32.5+9.6×BSA; left kidney area (95th percentile), 12.6+31.7×BSA; right kidney area (5th percentile), 16.1+18.5×BSA; right kidney area (95th percentile), 32.6+22.2×BSA.
conclusionsRegression equations have been developed, which define the upper and lower limits of renal size from 99mTc-MAG3 images and may assist in the detection of unsuspected bilateral increases or decreases in renal size.
