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

backgroundThere continues to be controversy regarding the optimal screening modality in patients with symptomatic cholelithiasis and suspected common bile duct (CBD) stones. The aim of this study was to assess the diagnostic accuracy of laparoscopic ultrasonography (LUS) compared to magnetic resonance cholangiopancreatography (MRCP).

methodsBoth LUS and MRCP were performed to evaluate the CBD stones and biliary anatomy in 200 patients undergoing laparoscopic surgery. Pre-, intra-, and postoperative data were collected prospectively and reviewed retrospectively.

resultsCoexisting CBD stones were identified in 64 of 200 (32%) patients by surgical exploration or postoperative ERCP. For the detection of CBD stones, LUS yielded a positive predictive value of 100%, a negative predictive value of 99.3%, a sensitivity of 98.4%, and a specificity of 100%. Preoperative MRCP had a positive predictive value of 87.9%, a negative predictive value of 95.5%, a sensitivity of 90.6%, and a specificity of 94.1%. The non-random concordance between MRCP and LUS was considered to be excellent with a kappa coefficient of 0.92 (p < 0.01).

conclusionsLUS can reduce the need for MRCP examination and can become the primary imaging method for the evaluation of CBD stones in laparoscopic surgery.
