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
backgroundBlood transfusion (BT) remains an integral part of oncosurgical management but is often associated with adverse outcomes and resource overuse. Predicting transfusion requirements before surgery could enhance patient blood management and optimize inventory utilization. This study aimed to identify perioperative predictors of BT and to develop a transfusion risk prediction tool for oncosurgical patients in a tertiary cancer care setting.
methodsA retrospective analysis was conducted on 578 patients who underwent major oncologic surgeries between December 2020 and April 2021. Demographic, surgical, and hematological parameters were compared between transfused and non-transfused groups. Factors associated with BT were analyzed using univariate and multivariate logistic regression. A transfusion risk prediction score model was constructed from independent predictors, and its discriminatory performance was assessed using the receiver operating characteristic (ROC) curve.
resultsAmong 578 patients, 73 (13%) required perioperative BT. Multivariate analysis identified preoperative hemoglobin (OR = 0.6; 95% CI: 0.52–0.71; p < 0.001) and duration of surgery (4–8 h: OR = 2.36; p = 0.03; > 8 h: OR = 19.16; p = 0.003) as independent predictors of transfusion. Type of surgery (deep or laparoscopic) showed significance on univariate but not on multivariate analysis. The model exhibited good discriminatory ability (AUC = 0.789; 95% CI: 0.762–0.860; p < 0.001). Patients with a cumulative score ≤ 8 had a higher probability of requiring BT.
conclusionPreoperative hemoglobin concentration and surgical duration are independent determinants of perioperative transfusion in oncosurgical patients. The proposed Transfusion Risk Prediction Score provides a simple, validated, and evidence-based tool to promote rational blood utilization and improve perioperative planning in cancer surgery.
