Correlation between the estimated GFR and SWRD score in patients with posterior urethral valves at King Abdul-Aziz University Hospital.

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
objectiveThe aim was to establish the reliability of the SWRD score as a predictor of both renal and bladder outcomes in posterior urethral valves. This retrospective study included 67 patients with PUVs at King Abdul-Aziz University Hospital. The score was calculated from voiding cystourethrogram before and after the relief of obstruction, and estimated glomerular filtration rates (eGFRs) were calculated as well.
resultsBased on Spearman correlations, both baseline eGFRs and SWRD scores can be possible predictors of long-term renal outcomes, as a significant positive correlation between the baseline eGFRs and the last eGFRs was found (p = 0.005). A significant negative correlation was also found between the SWRD score calculated before the intervention and the last eGFRs (p = 0.02). Additionally, the baseline SWRD scores can be possible predictors of short-term bladder outcomes, as the correlation analysis showed a positive relationship between the baseline SWRD scores and the SWRD scores calculated within 2 months after the intervention (p < 0.0001). A significant decrease in SWRD scores and eGFRs was found from before to after the intervention, regardless of the type of intervention. In conclusion, the SWRD scoring system proved to be a potentially promising tool in the anticipation of the clinical outcomes of PUVs.
