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 risk factors and prognostic implications of retrieving fewer than 12 lymph nodes in patients undergoing laparoscopic/robot-assisted right colectomy remain unclear.

methodsA total of 993 patients with Stage II/III right-sided colon cancer who underwent minimally invasive surgery between 2016 and 2024 were reviewed. Patients were divided into two groups: those with < 12 retrieved lymph nodes (low lymph node [L-LN] group, n = 139) and those with ≥ 12 retrieved lymph nodes (high lymph node [H-LN] group, n = 854). The clinicopathological characteristics and prognosis were compared between the groups.

resultsA multivariate analysis revealed that BMI > 25 kg/m

conclusionIn minimally invasive right colectomy, a high BMI and clinically node-negative disease were associated with a reduced number of dissected lymph nodes. As potentially inadequate dissection may contribute to a poor prognosis, adjuvant therapy should be considered in selected patients.
