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 hypothesisStrongyloides stercoralis is a neglected parasitic infection endemic to tropical regions, with rising prevalence in Europe. In kidney transplant (KTX) recipients, high-dose corticosteroids can induce a hyperinfection syndrome, which carries high mortality but is preventable with anthelminthic therapy. Screening for S. stercoralis is currently not included in pre-KTX protocols in Europe. This study assessed the prevalence of S. stercoralis among all haemodialysis patients in Vienna.
methodsAll consenting haemodialysis patients in Vienna (n = 704) underwent enzyme-linked immunosorbent assay testing for S. stercoralis immunoglobulin G (IgG). A detailed questionnaire captured soil exposure, medical and transplant history, travel, symptoms and immunosuppressive therapy. Positive serologies were confirmed at the Austrian reference centre for parasitology and in case of positivity followed by stool examination for larvae.
resultsOf 704 patients, 50 (7.1%) were seropositive for S. stercoralis IgG, including 4 with prior KTX; stool examination showed larvae in one case. Male sex [odds ratio (OR) 6.18, 95% confidence interval (CI) 1.44-26.54], absolute or relative eosinophilia (≥0.19 × 10⁹/L, ≥1.95%; area under the curve = 0.87 and 0.84), and birth in the Middle East and North Africa (OR 4.75, 95% CI 1.26-17.93) were independently associated with seropositivity, while birth in Western Europe was protective (OR 0.51, 95% CI 0.29-0.91; P = .023). Males were more likely to report occupational soil exposure (P = .002). Travel history, pet ownership, soil contact, gastrointestinal symptoms, pruritus, C-reactive protein and immunosuppression were not associated with seropositivity.
conclusionsRelevant S. stercoralis seroprevalence was found in a Central European haemodialysis population. Implementation of targeted screening for S. stercoralis should be considered in pre-KTX protocols in Europe.
