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
backgroundTo identify location and number of insulinomas before operation is very important for improving the cure rate. The objective of the study was to assess performance of CT during celiac artery angiography for preoperative localization of clinically suspected small insulinomas (< 2 cm in diameter).
methodsFrom January 2013 to November 2016, 42 patients with hypoglycemic symptoms underwent celiac artery angiography, superior mesenteric artery angiography and CT during celiac artery angiography by a combined CT/digital subtraction angiography system, MIYABI Angio CT plus an Artiszeeceiling (SIEMENS, Germany). Patient group consisted of 13 males and 29 females, age 17-69 years (average, 45.4 ± 13.5 y). After diagnosis, all 42 patients were operated. Obtained images were retrospectively analyzed and compared with findings from post-operation pathology.
resultsAll interventional radiology procedures were performed successfully with no complications. Sensitivity of angiography alone for insulinoma was 76.1% (32/42), at combined CT/digital subtraction angiography, 4 more nodules were found (sensitivity, 85.7%, 36/42), while 6 false-negatives were observed (all false negative lesions were less than 2 cm). A total of 64 ml to 80 ml contrast media was used per patient.
conclusionCT during celiac artery angiography is a sensitive diagnostic procedure for localizing insulinomas. Combined with angiography, it can prioritize the pancreatic region for exploration and guide a pancreatic resection.
trial registrationEthical approval was obtained from the Hospital Research Ethics Committee. Informed consent was obtained from all patients included in the study. Duan Feng, Bai Yan-hua and Cui Li are co-first authors.
