Utility of Ureteric Jets as an Adjuvant Diagnostic Modality in Children with Ureteropelvic Junction Obstruction: A Systematic Review and Meta-analysis.
Review in Journal of Indian Association of Pediatric Surgeons. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Ureteropelvic junction obstruction (UPJO) is a common cause of pediatric hydronephrosis, yet only one-third of affected children require surgery. Differentiating obstructive from non-obstructive cases remains challenging with current imaging methods. This systematic review and meta-analysis evaluated the role of ureteric jets, assessed via color Doppler ultrasonography (USG), as an adjuvant diagnostic modality to complement gray-scale USG in children with UPJO. Materials and Methods: A systematic search of PubMed, Embase, Scopus, and Web of Science databases was conducted to identify studies reporting on ureteric jet frequency (UJF) in UPJO. Standardized mean difference (SMD) with 95% confidence intervals (CI) was calculated for the pooled data, while the Results: Five studies (111 patients) met inclusion criteria. Ureteric jets were absent in 67.3% of UPJO cases, with diagnostic accuracy reaching 94%. Meta-analysis revealed a significant reduction in UJF in obstructed kidneys (SMD = -2.01, 95% CI: -3.09 to -0.94, Conclusions: The current systematic review demonstrated the absence of ureteric jets and a significant reduction in the UJF in the obstructed kidneys. However, due to heterogeneity among the included studies, further studies are needed to standardize the protocols before any definite conclusions are drawn.
