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
backgroundThrombocytopenia may result from either decreased platelet production (hypoproductive) or increased peripheral platelet destruction (hyperdestructive), and distinguishing between these mechanisms is essential for appropriate clinical management. Bone marrow examination remains the reference standard but is invasive and not always feasible. Platelet indices generated by automated hematology analyzers may provide a simple, non-invasive alternative for the initial evaluation of thrombocytopenia.
methodsThis hospital-based cross-sectional study included 150 patients with mild to moderate thrombocytopenia (platelet count 50-<150 × 10³/µL) attending a tertiary care teaching hospital in North India between 2024 and 2025. Platelet count, mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (PCT), and platelet large cell ratio (P-LCR) were measured using automated hematology analyzers. Patients were classified as having hyperdestructive (n = 114) or hypoproductive (n = 36) thrombocytopenia based on clinical evaluation and relevant laboratory investigations. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance of platelet indices.
resultsMPV, PDW, PCT, and P-LCR were significantly higher in patients with hyperdestructive thrombocytopenia than in those with hypoproductive thrombocytopenia (all p < 0.01). PDW (AUC = 0.747) and MPV (AUC = 0.745) demonstrated the best diagnostic performance. MPV showed the highest specificity (83.3%) at a cut-off value of 12.15 fL, whereas PCT demonstrated the highest sensitivity (78.1%) but relatively low specificity (38.9%). Plateletcrit showed a moderate positive correlation with platelet count (r = 0.464, p < 0.001).
conclusionsMPV and PDW demonstrated good diagnostic performance in differentiating hyperdestructive from hypoproductive thrombocytopenia and may serve as useful adjunctive markers during the initial evaluation of thrombocytopenic patients. As routinely available parameters obtained from complete blood count analysis, these indices may support clinical decision-making when interpreted alongside clinical and laboratory findings. Further multicenter studies are needed to validate these findings and establish standardized diagnostic cut-off values.
