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

objectiveFollowing the introduction of robot-assisted thoracoscopic surgery (RATS) as a health insurance-covered treatment in Japan, we investigated the current status and impact of the expansion of the indications for RATS for mediastinal tumors.

methodsBetween 2018 and 2022, 209 cases of total mediastinal tumor resection were performed in our hospital. The study period was divided into the first half (January 2018 to June 2020) and the second half (July 2020 to December 2022), and perioperative parameters were compared between the two groups.

resultsNinety-six surgical procedures were performed in the first half and 113 in the second half. The percentage of RATS approach was significantly higher in the second half compared with the first half (P < 0.001). Indications for RATS in the second half compared with the first half were significantly increased in patients with stage II (P < 0.001) and stage III (P = 0.026) thymomas, tumor diameter ≥ 50 mm (P < 0.011), and patients undergoing extended thymectomy for myasthenia gravis (P < 0.009). In respect of short-term postoperative parameters, the estimated intraoperative blood loss (P < 0.035), postoperative drain duration (P < 0.037), and postoperative hospital stay (P < 0.011) were significantly lower in the second half than in the first half.

conclusionsRATS has recently been expanded for mediastinal tumors with improved short-term outcomes in our hospital after health insurance was applied in Japan. In the future, it will be necessary to discuss the further expansion of its indications by taking into account safety and long-term outcomes.
