Extrahepatic cholestasis associated with paracoccidioidomycosis: Challenges in the differential diagnosis of biliopancreatic neoplasia.
Article in World journal of gastrointestinal oncology, 2024. 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
backgroundParacoccidioidomycosis (PCM) may involve the hepatic pedicle and peripancreatic lymph nodes, cause damage to the bile duct and manifest, exceptionally, in combination with extrahepatic cholestasis (EHC), making investigation and treatment challenging.
aimTo investigate the management of patients with visceral PCM admitted with EHC.
methodsAll patients diagnosed with PCM treated in a public, tertiary teaching hospital between 1982 and 2020 were retrospectively evaluated. Those also identified with EHC were allocated to two groups according to the treatment approach for the purpose of comparing clinical, laboratory, and imaging findings, resources used for etiological diagnosis, treatment results, and prognosis. Statistical analyses were performed using the linear mixed-effects model (random and fixed effects), which was adjusted using the PROC MIXED procedure of the SAS
resultsOf 1645 patients diagnosed with PCM, 40 (2.4%) had EHC. Of these, 20 (50.0%) lived in the rural area and 29 (72.5%) were men, with a mean age of 27.1 years (3-65 years). Jaundice as first symptom and weight loss of at least 10 kg were observed in 16 patients (40.0%), and a mass in the head of the pancreas was observed in 8 (20.0%). The etiological diagnosis was made by tissue collection during surgery in 4 cases (10.0%) and by endoscopic methods in 3 cases (7.5%). Twenty-seven patients (67.5%) received drug treatment alone (Group 1), whereas 13 (32.5%) underwent endoscopic and/or surgical procedures in combination with drug treatment (Group 2). EHC was significantly reduced in both groups (40.7% in Group 1, with a mean time of 3 months; and 38.4% in Group 2, with a mean time of 7.5 months), with no statistically significant difference between them. EHC recurrence rates, associated mainly with treatment nonadherence, were similar in both groups: 37% in Group 1 and 15.4% in Group 2. The mortality rate was 18.5% in Group 1 and 23% in Group 2, with survival estimates of 71.3% and 72.5%, respectively, with no statistically significant difference.
conclusionAlthough PCM-related EHC is rare, it needs to be included in the differential diagnosis of malignancies, as timely treatment can prevent hepatic and extrahepatic sequelae.
