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
Background: This study aimed to evaluate and compare the diagnostic value of C-reactive protein (CRP), procalcitonin (PCT), neutrophil count (NC), and neutrophil-to-lymphocyte ratio (NLR) in peripheral blood for detecting bacterial infections in patients with non-small cell lung cancer (NSCLC) following chemotherapy. Methods: A total of 122 NSCLC patients treated at our hospital between October 2021 and October 2024 were enrolled. Of these, 72 patients with confirmed bacterial infections post-chemotherapy were assigned to the infection group, while 50 patients without infections were included in the non-infection group. General clinical data, overall survival, and levels of CRP, PCT, NC, and NLR were compared between groups. Results: Levels of CRP, PCT, NC, and NLR were significantly higher in the infection group compared to the non-infection group (P<0.05). There was no significant difference in overall survival between the two groups (P=0.749). Receiver operating characteristic (ROC) curve analysis showed that all four biomarkers had statistically significant diagnostic value (P<0.05), with PCT demonstrating the highest AUC (1.000), followed by NLR (0.981). Conclusions: PCT and NLR are valuable biomarkers for diagnosing bacterial infections in NSCLC patients after chemotherapy. Due to their complementary diagnostic strengths, PCT offers high specificity and NLR high sensitivity, and their combined use may enhance early detection and improve clinical decision-making.
