Perioperative outcomes of sinusoidal obstruction syndrome in patients undergoing liver resection for colorectal metastases after neoadjuvant chemotherapy: a retrospective cohort research.

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
Purpose: We investigated the factors that affect the occurrence of sinusoidal obstruction syndrome (SOS) and the effect of SOS on the patient's perioperative outcomes through histological review of liver resection specimens from patients who underwent chemotherapy. Methods: From December 2007 to December 2020, liver specimens from patients who underwent liver resection for colorectal liver metastasis after neoadjuvant chemotherapy were analyzed regarding liver damage in the nontumorous lesion. Through pathological review, patients with grade 1-3 sinusoidal dilatation were categorized into the SOS (+) group, compared to a control group (grade 0, SOS [-]). Results: Of 286 patients, 175 were included. Preoperative factors were similar between the groups. Although not statistically significant, the SOS (+) group had a shorter chemotherapy-free interval before resection (7.96 weeks Conclusion: SOS development during liver surgery is associated with increased intraoperative blood loss, transfusion volume, and liver surgery-specific complications and has a higher risk of early recurrence and decreased overall survival. Thus, it is crucial to exercise caution during liver surgery in these patients.
