1 · What the graph read from 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.

2 · The registry

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

objectivesSarcopenia involves several mechanisms, including age-related changes, nutritional deficiencies, and inflammation, and is associated with unfavorable clinical outcomes. However, the significance of skeletal muscle index (SMI) and immune-nutritional status for patients with early-stage non-small cell lung cancer (NSCLC) remains unclear. This retrospective study was performed to investigate associations between preoperative SMI based on computed tomography (CT) at the L1 level and immune-nutritional status, and whether these factors correlated with surgical outcomes.

methodsWe retrospectively investigated 386 patients with stage I-II NSCLC who underwent curative anatomical pulmonary resection. SMI was assessed on CT at the L1 level and patients were divided into low-SMI (n = 97) and high-SMI (n = 289) groups. We examined the significance of SMI for postoperative outcomes and evaluated correlations between SMI and clinical characteristics, including immune-nutritional status.

resultsLow SMI was significantly associated with body mass index and geriatric nutritional risk index. Five-year overall survival rate was significantly lower in the low-SMI group (66.0%) than in the high-SMI group (82.2%, P = 0.004). Multivariate analysis revealed SMI (hazard ratio [HR] 1.850; 95% confidence interval [CI] 1.091-3.135; P = 0.022) and prognostic nutritional index (PNI) (HR 2.031; 95% CI 1.231-3.352; P = 0.006) as independent predictors of overall survival. Low SMI correlated significantly with postoperative complications (P = 0.024).

conclusionsLow preoperative SMI based on CT at the L1 level appears associated with poor prognosis and postoperative complications among patients with early-stage NSCLC. PNI is also an independent prognostic factor for surgical outcomes.
