Ultrasound findings in EHEC-associated hemolytic-uremic syndrome and their clinical relevance.
Article in International urology and nephrology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeHemolytic-uremic syndrome (HUS) and acute kidney injury (AKI) after infection with Shiga toxin-producing E. coli (EHEC) are clinically important complications. We present a retrospective analysis of abdominal ultrasound findings in patients with HUS caused by EHEC O104:H4 (n = 41).
methodsWe assessed intrarenal resistance indices and quantitated kidney parenchymal density by the kidney/liver intensity ratio using computer-based image analysis. Findings in EHEC-HUS were compared to those in AKI due to other reasons (n = 60) and 19 healthy volunteers.
resultsKidneys in EHEC-HUS patients showed severe morphologic changes with striking parenchymal echogenicity. Renal resistance index was increased in HUS (0.80 ± 0.08) compared to patients with AKI due to glomerulopathy (0.69 ± 0.08, p < 0.001) or patients with other causes of AKI (0.74 ± 0.10, p < 0.01). Parenchymal density was increased in EHEC-HUS (1.39 ± 0.35) compared to AKI due to glomerulopathy (1.18 ± 0.20, p < 0.05), other causes of AKI (1.12 ± 0.21, p < 0.001) and healthy controls (0.86 ± 0.16, p < 0.001). Patients with atypical HUS showed increased parenchymal density (1.43 ± 0.37), similar to those with EHEC-HUS. EHEC-HUS patients who required dialysis treatment had higher parenchymal density (1.58 ± 0.08) compared to those without dialysis (1.14 ± 0.05, p = 0.0004). Extrarenal findings in EHEC-HUS included hepatomegaly (45%), splenomegaly (39%), ascites (84%) and pleural effusions (84%).
conclusionsPatients with EHEC-HUS had a characteristic constellation of morphologic abnormalities on ultrasound examination, indicating that the effects of HUS are not limited to the kidney but include multiple organs, possibly mediated through systemic capillary leakage. Assessment of parenchymal echogenicity contributes to the differential diagnosis of AKI. Parameters reflecting renal perfusion correlated with severity of disease and thus may have prognostic value in future patient evaluation.
