Reciprocity between lymphadenectomy quality and adjuvant chemotherapy compliance in gastric cancer: post hoc analysis of two randomized controlled trials.
Article in Surgical endoscopy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
objectiveTo investigate the effect of intraoperative lymph node (LN) dissection and postoperative adjuvant chemotherapy on the overall survival (OS) of gastric cancer (GC) patients and their reciprocity.
methodsLN noncompliance was defined as the absence of more than one LN station, as described in the protocol for D2 lymphadenectomy in the Japanese Gastric Cancer Association. The definition of adjuvant chemotherapy (AC) noncompliance was that the chemotherapy planned dose does not meet the requirements.
resultsKaplan-Meier survival curves showed that the OS of patients with major LN noncompliance was significantly lower than that of patients with nonmajor LN noncompliance, and the OS of AC noncompliance patients was significantly lower than that of AC compliance patients. If there was nonmajor LN noncompliance during surgery, the OS of patients with AC compliance was significantly higher than that of patients with AC noncompliance (P = 0.035). In the case of major LN noncompliance during surgery, there was no statistically significant difference in OS between those with AC compliance and those with AC noncompliance (P = 0.682). Multivariate Cox regression analysis including AC noncompliance indicated that major LN noncompliance was an independent prognostic factor for poor OS (P = 0.012), while AC noncompliance was not an independent prognostic factor for OS (P = 0.609).
conclusionAdequate lymph node dissection and adjuvant chemotherapy are both key steps to improve the awful prognosis of GC patients. Adjuvant chemotherapy may fail to remedy the poor prognosis caused by major LN noncompliance.
