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

aimsThe safety and efficacy of pancreaticoduodenectomy (PD) in patients over the age of 80 years remain controversial. We aimed to examine post-PD outcomes and to determine the age limit for PD.

methodsPatients were divided into two subgroups: the younger (<80 years) group and octogenarian (≥80 years) group. We retrospectively evaluated the clinical benefit of PD for periampullary diseases in the younger and octogenarian groups, focusing on short- and long-term outcomes.

resultsFrom March 2005 to December 2018, 586 consecutive surgically curable patients with diagnosed periampullary diseases were studied, among whom 122 (20.8%) were ≥80 years old. The general preoperative physical condition (G8 screening, instrumental activities of daily living, and Charlson comorbidity index) and nutritional status were significantly worse in the octogenarian group. However, there were no significant differences between the younger and octogenarian groups in postoperative severe complication rates (34% vs 36%) or perioperative mortality rates (1.5% vs 0.0%). We observed significantly poorer 3-, 5-, and 10-year overall survivals in the octogenarian group than in the younger group (

conclusionsIt is important to carefully determine the indication for PD in octogenarian patients with periampullary diseases, although patient age over 80 years should not be a contraindication for PD.
