Sono-graphic Rim Sign in Postpartum Renal Cortical Necrosis: Experience at a Tertiary Care Centre.

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: Kidney biopsy or contrast studies are required to diagnose acute renal cortical necrosis (RCN). Both procedures may be potentially delayed in the postpartum setting. Contrast-enhanced ultrasound (CEUS) is a potential alternative for these patients but remains limited in availability. Due to sparse literature and the rarity of RCN, the role of conventional B-mode ultrasound (USG) in diagnosing RCN remains unexplored. Materials and Methods: This retrospective study involved postpartum patients with RCN who underwent kidney biopsy at a tertiary care center. Medical records and B-mode USG kidney images of all 23 patients with postpartum RCN over the past 24 months were retrieved. Gray-scale B-mode USG images of the kidney were assessed for size, presence of sonographic hypoechoic rim, USG kidney timing, echogenicity, and cortico-medullary differentiation. Results: Among the 23 patients, sonographic hypoechoic rim was observed in 6 patients (26.1%). USG kidney timing ranged from 1.1 to 8 weeks, and kidney length varied from 9.0 to 10.8 cm. There were significant differences in mean USG kidney timing and mean kidney length between patients with and without hypoechoic rim ( Conclusion: Despite its lower sensitivity, the sonographic rim sign is an important diagnostic feature of postpartum renal cortical necrosis. In point-of-care ultrasonography, it should be looked for early in the disease course, especially in cases of postpartum anuric acute kidney injury.
