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

backgroundPancreaticobiliary maljunction (PBM) is a congenital anomaly in which the pancreatic and bile ducts join outside the duodenal wall.

resultsThe operative time was 480 min, including 210 min for Retlap, with 40 mL blood loss. The postoperative course was uneventful, and she was discharged on postoperative day 14. Pathology confirmed gallbladder carcinoma with single-node metastasis. At this writing, after adjuvant chemotherapy, the woman has remained recurrence-free 3 years.

conclusionAlthough additional trocars and steps are required, Retlap for PBM may enable safe bile duct transection just above the pancreatobiliary junction and facilitate lymphadenectomy, providing excellent visualization and stable maneuverability.
