Prognostic Significance of Tumour Budding and Tumour-infiltrating Lymphocytes in Gallbladder Carcinoma.
Article in Journal of the West African College of Surgeons. 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 and Objective: Gallbladder cancer (GBC) frequently occurs at an advanced stage, with histological sub-type, tumour size, grade of differentiation, lymphovascular invasion (LVI), perineural invasion (PNI), nodal metastases, and surgical resection margins impacting prognosis. Tumour budding (TB) and tumour-infiltrating lymphocytes (TILs) have emerged as novel prognostic markers in various cancers. Materials and Methods: The study included gallbladder specimens operated between January 2016 and May 2022. Clinical data were retrieved from the institutional archive. Histopathological slides were reviewed for histological differentiation, neck resection margin status, LVI, PNI, serosal involvement, lymph node metastases, etc. TILs and TB were graded according to established guidelines. Statistical Package for Social Sciences version 21.0 was utilised to analyse the data. Results: Seventy-nine gallbladder adenocarcinoma (pT1 = 25.32%, pT2 = 34.18%, pT3 = 40.50%) cases were examined. Surgical resection margin, LVI, PNI, serosal involvement, and nodal metastasis were present in 13.92% (11/79), 26.58% (21/79), 29.11% (23/79), 41.77% (33/79), and 30.38% (24/79) cases, respectively; 43.04% (34/79), 36.71% (29/79), and 20.25% (16/79) of cases had TIL-1, TIL-2, and TIL-3, respectively. Bd1, Bd2, and Bd3 were noted in 63.29% (50/79), 18.99% (15/79), and 17.72% (14/79), of cases, respectively. Higher-grade TB was linked with poorer tumour histology ( Conclusion: Age, less differentiated histological grade, pT category, LVI, and higher TB grade were independently associated with worse 4-year overall survival. Higher TB correlates with high-risk clinicopathological features and inferior overall survival, while higher TILs are associated with lower GBC histological grade and LVI incidence.
