1 · What the graph read from it

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.

2 · The registry

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

purposeTo evaluate the diagnostic potential of choline measurements by in vivo magnetic resonance spectroscopy (MR spectroscopy) for diagnosis of renal masses.

methodsTwenty-eight patients with 29 renal lesions underwent prospectively preoperative 3 T MR spectroscopy of renal masses before diagnostic tissue confirmation. A respiratory-triggered single-voxel MR spectroscopy was performed in these masses using the point-resolved spectroscopy (TR, 2,000 ms, TE, 135 ms) sequence. The spectra were analyzed for choline resonances at 3.23 ppm, which were normalized by the noise outside the diagnostic range of the spectra. Image and spectra analyses were conducted blinded to all patient-related data. Histological results of the surgical resection or image-guided biopsy specimen were defined as the standard of reference. Appropriate statistical tests were used.

resultsSeventeen lesions were histopathologically malignant, and 12 lesions were benign. Mean choline SNR in malignant lesions was 2.9 and 1.33 in benign lesions (P = 0.019). ROC analysis revealed an area under the curve of 0.721 and SE 0.0763 with a P value of 0.0038. A Cho SNR ≥2 as cutoff for malignancy resulted in a sensitivity and specificity of 52.9 % (95 % CI 27.8-77.0 %) and 91.7 % (61.5-99.8 %), respectively. Although not significant, choline was observed more regularly in G3 (4 out of 5) compared with G2 (5 out of 12) RCC (P > 0.05).

conclusionsWe could demonstrate the potential role of in vivo MR spectroscopy as a tool for differentiating benign from malignant masses with a high positive predictive value of 90 %. Furthermore, choline may be a biomarker of RCC aggressiveness.
