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
backgroundCommon neonatal etiologies of acute kidney injury (AKI) include renal vein and inferior vena cava thromboses, maternal use of nonsteroidal antiinflammatory drugs, and congenital renal disease. The incidence of renal vein thrombosis is estimated to be 0.5 per 1,000 neonatal intensive care unit admissions, with approximately half of cases extending to the inferior vena cava and with unilateral disease being significantly more common than bilateral. Data on abdominal venous thromboembolism in pediatric patients are limited, and the clinical presentation of renal vein thrombosis can vary, although most patients have at least one of the three cardinal signs: hematuria, thrombocytopenia, or abdominal mass. CASE REPORT: We present the case of a 5-month-old female transferred to our pediatric intensive care unit from an outside hospital with AKI and significant uremia (creatinine 6.01 mg/dL, blood urea nitrogen >200 mg/dL) secondary to inferior vena cava, bilateral renal vein, and bilateral renal artery thromboses. The patient was started on a heparin drip and subsequently underwent mechanical thrombectomy of her inferior vena cava and right renal vein in addition to site-directed tissue plasminogen activator to her renal veins, renal arteries, and inferior vena cava. Following the procedure, she developed severe coagulopathy and became hemodynamically labile. The coagulopathy was corrected, but further anticoagulation to prevent further thrombus propagation was not sustainable in the face of ongoing bleeding and hemodynamic instability, so the decision to withdraw mechanical support was made.
conclusionBecause of the varied presentations of renal vein thrombosis and because prompt intervention significantly improves survival and renal outcomes, a high index of suspicion is warranted when risk factors and any of the three cardinal features of renal vein thrombosis are present.
