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
purposeAdrenal metastasectomy is a common local treatment for adrenal metastases, with a lack of serum prognostic factors. Here, we identified the prognostic significance of preoperative hemoglobin and albumin levels in patients undergoing adrenal metastasectomy. MATERIALS AND
methodsData from 93 patients who underwent adrenal metastasectomy were assessed retrospectively. Receiver operating characteristic (ROC) curve analysis was used to determine the optimal cutoff values of hemoglobin and albumin for survival. Overall survival (OS) and disease-free survival (DFS) were evaluated using the Kaplan-Meier method, thereafter Cox regression models and subgroup analyses were applied to adjust confounding factors. A risk stratification developed by joint use of serum hemoglobin and albumin levels was also tested.
resultsOptimal cut-off points were 130.5 g/L and 44.8 g/L for hemoglobin and albumin, respectively. Multivariate Cox regression analysis identified decreased hemoglobin (HR [95% CI]: 0.41 [0.18-0.91], P = 0.029) and albumin (HR [95% CI]: 0.12 [0.02-0.88], P = 0.038) levels as independent factors for poorer OS. Patient with both decreased hemoglobin and albumin levels had the worst OS (P = 0.001) and DFS (P = 0.001) than other risk groups. Subgroup analyses proved decreased hemoglobin and albumin levels predicted poorer OS independent of cancer types.
conclusionsPreoperative hemoglobin and albumin levels may serve as prognostic predictors after adrenal metastasectomy. A prognostic model that combines hemoglobin and albumin can improve accuracy in predicting patient outcomes and be easily implemented in clinical practice.
