Prognostic Role of a New Index Tested in European and Korean Advanced Biliary Tract Cancer Patients: the PECS Index.
Article in Journal of gastrointestinal cancer, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
aimThe aim of the present study is to evaluate a new index (PECS (PsECogSii)index) influenced by PS ECOG and systemic immune-inflammation index (SII) in unresectable locally advanced or metastatic BTC patients treated with first-line chemotherapy.
methodsThis multicenter, international, study was conducted on a training cohort of 130 patients and in three European and Korean validation cohorts The PECS index was calculated as ECOG × SII index (neutrophil count × platelet count/lymphocyte count). Event-time distributions were estimated using the Kaplan-Meier method and survival curves were compared using the log-rank test.
resultsIn the training cohort, the median overall survival (mOS) was 13.2 months, 8.7 months, and 3.8 months for patients with PECS-0, PECS-1, and PECS-2, respectively (PECS-0: HR = 1; PECS-1: HR 1.41; PECS-2: HR 3.23) (p < 0.0001). In the first validation cohort, the mOS was 12.8 months, 10.1 months, and 5.3 months for patients with PECS-0, PECS-1, and PECS-2, respectively (PECS-0: HR = 1; PECS-1: HR 1.29; PECS-2: HR 2.40) (p < 0.0001). In the second validation cohort, the mOS was 21.2 months, 10.2 months, and 3.0 months for patients with PECS-0, PECS-1, and PECS-2, respectively (PECS-0: HR = 1; PECS-1: HR 2.25; PECS-2: HR 9.00) (p < 0.0001). In the third validation cohort, the median OS was 15.5 months, 7.5 months, and 3.7 months for patients with PECS-0, PECS-1, and PECS-2, respectively (PECS-0: ref HR = 1; PECS-1: HR 2.14; PECS-2: HR 5.00) (p < 0.0001). Multivariate analysis in all cohorts confirmed the PECS index as an independent prognostic factor for OS.
conclusionsThe easy assessment, low cost, and reproducibility make PECS index a promising tool to assess the prognosis of BTC patients in future clinical practice.
