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: Migraine is increasingly recognized as a neuroinflammatory disorder characterized by trigeminovascular activation and cytokine-mediated nociceptive sensitization. While leukocyte-derived indices such as the neutrophil-to-lymphocyte ratio (NLR) and systemic immune-inflammation index (SII) reflect dynamic inflammatory responses, the hemoglobin-albumin-lymphocyte-platelet (HALP) score represents a composite immunonutritional marker associated with chronic systemic inflammation. However, its potential relevance in migraine remains unclear. Methods: In this retrospective cross-sectional study, 115 patients with migraine were included. HALP, NLR, platelet-to-lymphocyte ratio (PLR), and SII were calculated from laboratory parameters obtained within ±14 days of clinical evaluation. Associations with clinical variables were analyzed using correlation and regression analyses. Discriminative performance for chronic versus episodic migraine was assessed using receiver operating characteristic (ROC) curve analysis with Youden index estimation. Results: Among the 115 included patients, 99 (86.1%) had episodic migraine and 16 (13.9%) had chronic migraine. HALP was not associated with monthly headache frequency, disease duration, or analgesic use and showed limited discriminative performance. In contrast, NLR and SII were significantly elevated in chronic migraine and demonstrated moderate discriminatory ability for differentiating chronic from episodic migraine (AUC = 0.734 and 0.723, respectively). However, these estimates should be interpreted cautiously given the relatively small chronic migraine subgroup. Conclusion: These findings suggest that migraine-related inflammatory processes may be more sensitively reflected by rapidly responsive leukocyte-derived indices than by composite immunonutritional markers such as HALP. The lack of association between HALP and clinical features may indicate that systemic inflammatory involvement in migraine is limited or variable, rather than persistently elevated.
