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

backgroundResection of the primary lesion with radical lymph node dissection is the most promising treatment avenue for patients with cancer. On the other hand, these procedures often induce excessive intraoperative blood loss (IBL) and require perioperative blood transfusion. The influence of IBL on the long-term postoperative outcomes of patients with digestive cancer is controversial. We investigated the impact of IBL on survival and recurrence after curative surgery in patients with colorectal cancer (CRC) in a single study group. PATIENTS AND

methodsIn total, 1,597 patients who underwent radical resection for CRC at three group hospitals between 2000 and 2019 were reviewed. Patients were classified into a group with high IBL (≥200 ml) or low IBL (<200 ml). The risk factors for disease-free (DFS) and overall (OS) survival were analyzed.

resultsA total of 489 and 1,108 patients were classified into the high and low IBL groups, respectively. The OS and DFS rates at 5 years after surgery were 89.3% and 63.4%, respectively, for the high IBL group and 96.9% and 77.8% for the low IBL group; these differences were statistically significantly (p<0.001). The multivariate analysis demonstrated that IBL was a significant independent risk factor for OS and DFS.

conclusionThe amount of IBL was associated with significant differences in the OS and DFS of patients with stage II/III CRC who received curative resection. The surgical procedure, surgical strategy, and perioperative care should be carefully planned to avoid causing IBL.
