Validation of S.T.O.N.E nephrolithometry and Guy's stone score for predicting surgical outcome after percutaneous nephrolithotomy.

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 validate and compare Guy's and S.T.O.N.E. scoring systems in predicting perioperative and postoperative outcome following percutaneous nephrolithotomy (PCNL). MATERIALS AND
methodsFrom November 2015 to June 2017, 190 patients with renal stones who underwent single tract unilateral PCNL in the prone position were included in our study. Guy's and S.T.O.N.E. nephrolithometry scores were calculated in each case based on preoperative computed tomography images. The association of these scoring systems with stone-free status, length of hospital stay, operative time, and postoperative complications was studied. Regression analysis was done, and receiver operating characteristic curves were plotted.
resultsMean S.T.O.N.E. and Guy's stone scores were 8.76 ± 2.29 and 2.70 ± 1.0, respectively. When compared with patients with residual stones, stone-free (SF) patients had significantly lower mean Guy's score (2.58 ± 1.01 vs. 3.23 ± 0.77 [P < 0.001]) and S.T.O.N.E. scores (8.44 ± 2.24 and 10.17 ± 2.0 [P < 0.001]), respectively. On logistic regression analysis, both Guy's score (odds ratio [OR] = 0.48,
conclusionBoth the S.T.O.N.E and Guy's scoring systems were found to predict the outcome of PCNL, either of these could be used in the routine clinical practice for patients' counseling.
