Inflammation-based Scores in Patients With Pheochromocytoma.
Article in The Journal of clinical endocrinology and metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundPheochromocytoma is associated with systemic inflammation but the underlying mechanisms are unclear. Therefore, we investigated the relationship between plasma metanephrine levels and hematological parameters-as a surrogate of inflammation-in patients with pheochromocytoma and the influence of preoperative α-blockade treatment. DESIGN AND
methodsWe retrospectively studied 68 patients with pheochromocytoma who underwent adrenalectomy (median age, 53 years; 64.7% females) and 2 control groups matched for age, sex, and body mass index: 68 patients with nonfunctioning adrenocortical tumors and 53 with essential hypertension. The complete blood count and several inflammation-based scores (neutrophil-to-lymphocyte ratio [NLR], platelet-to-lymphocyte ratio [PLR], lymphocyte-to-monocyte ratio [LMR], systemic-immune-inflammation index [SII], prognostic-nutrition index) were assessed in all patients and, in a subset of pheochromocytomas, after adrenalectomy (n = 26) and before and after preoperative α-blockade treatment (n = 29).
resultsA higher inflammatory state, as indicated by both complete blood count and inflammation-based scores, was observed in patients with pheochromocytoma compared with nonfunctioning adrenocortical tumors and essential hypertension. Plasma metanephrine levels showed a positive correlation with NLR (r = 0.4631), PLR (r = 0.3174), and SII (r = 0.3709) and a negative correlation with LMR (r = 0.4368) and prognostic-nutrition index (r = 0.3741), even after adjustment for age, sex, ethnicity, body mass index, and tumor size (except for PLR). After adrenalectomy, we observed a reduction in NLR (P = .001), PLR (P = .003), and SII (P = .004) and a concomitant increase in LMR (P = .0002). Similarly, α-blockade treatment led to a reduction in NLR (P = .007) and SII (P = .03).
conclusionInflammation-based scores in patients with pheochromocytoma showed pro-inflammatory changes that correlated with plasma metanephrine levels and are ameliorated by adrenalectomy and α-blockade.
