Effect of peri-operative blood transfusions on long-term prognosis of patients with colorectal cancer.
Article in Blood transfusion = Trasfusione del sangue, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPatients with colorectal cancer often present with anaemia and require red blood cell transfusions (RBCT) during their peri-operative course. Evidence suggests a significant association between RBCT and poor long-term outcomes in surgical patients, but the findings in colorectal cancer are contradictory. MATERIAL AND
methodsThe aim of this retrospective, single-centre, cohort study was to investigate the prognostic role of peri-operative RBCT in a large cohort of patients with stage I-III colorectal cancer submitted to curative surgery between 2005 and 2017. The propensity score matching technique was applied to adjust for potential confounding factors.
resultsAmong 1,414 patients operated within the study period, 895 fulfilled the inclusion criteria: 29.6% (n=265) received peri-operative RBCT. The group that received peri-operative RBCT was significantly older (p<0.001), had more comorbidities (p<0.001), more advanced tumours (p<0.001) and more colon tumours (p=0.002) and stayed in hospital longer (p<0.001). Post-operative mortality was 7-fold higher (2.3 vs 0.3%, p=0.01) in this group. Survival outcomes were significantly worse in the group receiving RBCT than in the group not receiving RBCT for both overall (64.5 vs 80.1%, p<0.001) and cancer-specific survival (74.3 vs 85.1%, p<0.001). On multivariable analysis, peri-operative RBCT was significantly associated with poorer overall survival (hazard ratio 1.51, p=0.009). When transfused and non-transfused cases were paired through the propensity score matching technique considering main clinico-pathological features, no differences in overall and cancer-specific survival were found. DISCUSSION: Our data suggest that, after adjustment for potential confounding factors, no significant association exists between RBCT and prognosis in colorectal cancer.
