Article in BMJ open, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05334251 (General Anesthesia or Combined Spinal-epidural Anesthesia With Ketofol Sedation in Colon Cancer Surgery?), which is not on this map. Cited by 7 papers, 1 of them a synthesis that pooled it.

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.

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.

Abstract

objectivesWhether epidural analgesia affects cancer outcomes remains controversial. Most previous investigations ignored the confounding potential of important pathological factors on cancer outcomes. This study aimed to assess the association between epidural analgesia and cancer recurrence or death after resections for colon cancer.

designRetrospective cohort study.

settingA single-medical centre in Taiwan.

participantsPatients with stage I through III colon cancer undergoing bowel resection and receiving either epidural analgesia or intravenous opioid analgesia from 2005 to 2014. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome was postoperative recurrence-free survival and secondary outcome was overall survival.

resultsA total of 2748 and 1218 patients were analysed before and after propensity score matching. Cox regression analyses did not demonstrate any association between epidural analgesia and recurrence or death after matching (HR 0.89, 95% CI 0.65 to 1.21 for recurrence; 0.72, 95% CI 0.48 to 1.09 for death). Independent prognostic factors for cancer recurrence and death were higher level of preoperative carcinoembryonic antigen, perioperative blood transfusion, advanced cancer stage and pathological lymphovascular invasion.

conclusionsNo definite association was found between epidural analgesia and risk of recurrence or death in patients undergoing colon cancer resection.
