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

purposeThe incidence of colorectal cancer (CRC) is increasing worldwide. Surgical resection is the primary treatment for localized cases with the aim of complete tumor removal and adequate lymph node dissection. Intracorporeal anastomosis (IA) has gained popularity in colorectal surgery; however, its oncological benefits over extracorporeal anastomosis (EA) remain unclear.

methodsThis retrospective study at Ehime University Hospital included 118 right-sided colon cancer patients (54 IA and 64 EA) treated between 2018 and 2023. Outcomes such as distal margin (DM) length and number of lymph nodes dissected were assessed.

resultsIn the IA group, the DM was significantly longer (117.9 ± 49.5 mm vs. 78.2 ± 30.1 mm, p < 0.001) and more lymph nodes were harvested (22.2 ± 10.0 vs. 18.2 ± 9.9, p = 0.031). A multivariate analysis identified IA as an independent factor for DM > 10 cm (odds ratio [OR] = 0.25, p = 0.001) and > 12 dissected lymph nodes (OR = 0.15, p = 0.006). Patients with IA resumed ingestion and defecation sooner, with shorter hospital stays.

conclusionsIA provides significant advantages for DM length and lymph node dissection, suggesting that it may be preferable for right-sided colon cancer surgery.
