Association of postoperative anaemia with prolonged hospital length of stay after upper gastrointestinal cancer surgery: a single-centre retrospective cohort study
Article in BJA open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Prolonged hospital length of stay (LOS) after major upper gastrointestinal (GI) cancer surgery is associated with increased morbidity, mortality, and healthcare costs. Perioperative anaemia is common in this population. This study examined whether reduced haemoglobin (Hb) is independently associated with prolonged LOS after elective upper GI cancer surgery. Methods: We conducted a retrospective observational cohort study of patients undergoing elective upper GI cancer surgery at a tertiary hospital in Western Australia. Pre-, intra-, and postoperative data were obtained from a prospective institutional database. Patients were dichotomised into expected-LOS and prolonged-LOS groups based on the procedure-specific median LOS. Multivariable logistic regression was used to identify factors independently associated with prolonged LOS. Results: A total of 111 patients were included; 26 (23.4%) had prolonged LOS. These patients had lower Hb intraoperatively (106.5±17.9 Conclusions: Postoperative Hb decline is independently associated with prolonged LOS after elective upper GI cancer surgery. These findings support prospective evaluation of patient blood management strategies in this population.
