Diagnostic value of immune indicators and cytokines in sepsis after percutaneous nephrolithotomy (PCNL).
Article in Journal of medical biochemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: To analyse the changes in and diagnostic value of immune indicators and cytokines in patients with sepsis after percutaneous nephrolithotomy (PCNL). Methods: Clinical information was gathered from 405 patients with calculi who underwent PCNL at our facility between January 2021 and December 2024. The patients were divided into a sepsis group (12 patients) and a non-sepsis group (393 patients) based on whether sepsis occurred after the operation. The levels of CD4+/CD 8 + cells, the neutrophil-to-lymphocyte ratio (NLR), soluble trigger receptor-1 (sTREM-1) in myeloid cells, procalcitonin (PCT), tumour necrosis factor-alpha (TNF-<span style="color: rgb(32, 33, 34); font-family: sans-serif; font-size: 16px; background-color: rgb(248, 249, 250);">α</span>), and interleukin-6 (IL-6) were measured in the two patient groups. The predictive value of the above indicators for sepsis was analysed via receiver operating characteristic (ROC) curves. Results: The number of patients with staghorn calculi in the sepsis group was greater than that in the nonsepsis group (P< 0.05). The NLR and sTREM-1 levels were greater in the sepsis group than in the nonsepsis group (all P< 0.05), and the CD 4+/CD 8+ ratio was lower in the sepsis group than in the nonsepsis group (P< 0.05). The levels of serum IL-6, TNF-<span style="color: rgb(32, 33, 34); font-family: sans-serif; font-size: 16px; background-color: rgb(248, 249, 250);">α</span> and PCT in the sepsis group were greater than those in the nonsepsis group (all P< 0.05). The area under the curve (AUC) for the combined prediction of sepsis after PCNL by each index was 0.996, with a predictive sensitivity of 91.3% and a specificity of 98.4%. Conclusions: The NLR, sTREM-1, IL-6, TNF-<span style="color: rgb(32, 33, 34); font-family: sans-serif; font-size: 16px; background-color: rgb(248, 249, 250);">α</span> and PCT in patients with sepsis after PCNL increased, whereas the CD 4+/CD 8+ ratio decreased. The combined detection of these levels is beneficial for guiding the early clinical prediction of postoperative sepsis in patients undergoing PCNL.
