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

aimTo evaluate the value of miniprobe sonography (MPS), spiral CT and MR imaging (MRI) in the tumor and regional lymph node staging of esophageal cancer.

methodsEight-six patients (56 men and 30 women; age range of 39-73 years, mean 62 years) with esophageal carcinoma were staged preoperatively with imaging modalities. Of them, 81 (94 %) had squamous cell carcinoma, 4(5 %) adenocarcinoma, and 1(1 %) adenoacanthoma. Eleven patients (12 %) had malignancy of the upper one third, 41 (48 %) of the mid-esophagus and 34 (40 %) of the distal one third. Forty-one were examined by spiral CT in whom 13 were co-examined by MPS, and forty-five by MRI in whom 18 were also co-examined by MPS. These imaging results were compared with the findings of the histopathologic examination for resected specimens.

resultsIn staging the depth of tumor growth, MPS was significantly more accurate (84 %) than spiral CT and MRI (68 % and 60 %, respectively, P<0.05). The specificity and sensitivity were 82 % and 85 % for MPS; 60 % and 69 % for spiral CT; and 40 % and 63 % for MRI, respectively. In staging regional lymph nodes, spiral CT was more accurate (78 %) than MPS and MRI (71 % and 64 %, respectively), but the difference was not statistically significant. The specificity and sensitivity were 79 % and 77 % for spiral CT; 75 % and 68 % for MPS; and 68 % and 62 % for MRI, respectively.

conclusionMPS is superior to spiral CT or MRI for T staging, especially in early esophageal cancer. However, the three modalities have the similar accuracy in N staging. Spiral CT or MRI is helpful for the detection of far-distance metastasis in esophageal cancer.
