Readmissions After Surgery for Colorectal Liver Metastases: A Propensity Score Analysis From the Colorectal Liver Operative Metastasis International Collaborative (COLOMIC).
Article in World journal of surgery, 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
backgroundReadmission is considered as a surgical quality indicator. More data regarding predictors of readmission and outcomes after surgery for colorectal liver metastasis are needed. Using a propensity score match to create a 1:2 match of cases:controls for 90-day. Readmission, the matching variables used for balance included age, tumor size, estimated blood loss, and type of resection (minor or major). T-tests were used for continuous measures, Fisher's exact test was used for categorical data, and the Kaplan-Meier method was used to estimate survival. p < 0.05 was considered significant.
methodsRetrospectively examined 935 patients with CLM from 2000 to 2018. Using a propensity score match to create a 1:2 match of cases:controls for 90-day. Readmission, the matching variables used for balance included age, tumor size, estimated blood loss, and type of resection (minor or major). T-tests were used for continuous measures, Fisher's exact test was used for categorical data, and the Kaplan-Meier method was used to estimate survival. p < 0.05 was considered significant.
results935 patients were included in the initial sample with 896 eligible for inclusion in the propensity matching. The average age of the population was 59% and 59% male. Overall readmission rate was 8.0%. Median time to readmission was 14 days. In the propensity score matched sample, readmitted patients had higher rates of organ space infection (28% vs 2% and p < 0.0001), bile leak (26% vs 1% and p < 0.0001), and liver failure (9% vs 2% and p = 0.042). There was no difference in LOS (7 days versus six days and p = 0.40), overall survival (median 39.7 vs 41.0 months and p = 0.79), or rate of adjuvant therapy (68% for both and p > 0.99).
conclusionPatients readmitted for intermediate and late complications after surgery for CLM can recover and receive adjuvant therapy with no adverse effect on overall survival. Organ space infection, bile leak, and liver failure are highly associated with readmission.
