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
introductionDetermining a surgical strategy for early-stage lung cancer requires an accurate histologic diagnosis. Immunohistochemistry (IHC) enables reliable diagnosis of histological types but requires more time and more tumor tissue slides than hematoxylin and eosin staining. We aimed to assess the clinical validity of a new rapid multiplex IHC technique utilizing alternating current (AC) mixing for intraoperative lung cancer diagnosis.
methodsForty-three patients who underwent radical resection of lung cancers were enrolled in a retrospective observational study. Frozen sections were prepared from lung tumor samples, and rapid IHC employing AC mixing was implemented alongside a multiplex IHC protocol targeting thyroid transcription factor-1 + cytokeratin 5, desmoglein 3 + Napsin A, and p63 + tripartite motif containing 29. We then evaluated the concordance between intraoperative diagnoses derived from rapid multiplex IHC and final pathology.
resultsThe concordance rate between the pathological diagnosis made with added rapid multiplex IHC and the final pathology was 93.0% (Cohen's 𝜅 coefficient = 0.860 and 95% CI: 0.727-0.993). When considering only adenocarcinoma and squamous cell carcinoma, the diagnoses were in agreement for all cases.
conclusionsWe suggest rapid multiplex IHC as a promising tool for determining surgical strategies for lung tumors.
