Dynamic magnetic resonance imaging in acute pyelonephritis.
Article in La Radiologia medica, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeThis study was conducted to evaluate the role and clinical impact of dynamic magnetic resonance imaging (MRI) in the diagnosis and follow-up of acute pyelonephritis (APN). MATERIALS AND
methodsWe retrospectively reviewed 442 consecutive renal MRI examinations (279 diagnostic and 163 follow-up) performed in 285 patients (mean age 42.17 years), 35 of whom were kidney transplant recipients with a clinical suspicion of APN.
resultsMRI showed signal abnormalities suggestive of APN in 125/244 (51.2%) patients with native kidneys. Except for two examinations performed without paramagnetic contrast material, the inflammatory foci appeared as areas of nonenhancement: single in 39/123 cases, multiple in 84/123, unilateral in 60/84 and bilateral in 24/84. Abscesses were present in 40/123 (32.5%) positive cases. During follow-up, we observed complete normalisation of MRI signs in 86/103 patients; 17/103 (16.5%) cases evolved into fibrosis and scarring. In 15/35 (42.8%) patients with transplanted kidney, MRI was positive for APN.
conclusionsRenal MRI is an effective tool for the diagnosis and follow-up of APN both in patients not at risk and those at higher risk, such as those with a transplanted kidney. The high costs of the examination are offset by better treatment planning and early complication detection.
