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
Several fruits have been identified as allergens and potential triggers for exacerbation of atopic dermatitis (AD). This study evaluated pineapple allergy and sensitization among adult patients with AD and examined the diagnostic accuracy of a locally produced pineapple allergen extract in skin prick tests (SPTs). A total of 30 adult patients with AD, with a mean age of 36.07±10.81 years, were enrolled in the study. Firstly, SPT was performed using a standard pineapple allergen extract manufactured by Astromed® (Astromed Inc., West Warwick, Rhode Island, USA). Subsequently, a second SPT was carried out with the pineapple allergen extract produced by the Teaching Industry Allergen Dr. Soetomo General Academic Hospital, Universitas Airlangga (Surabaya, Indonesia). Data were analyzed for diagnostic test accuracy and agreement. The local pineapple SPT had a sensitivity of 33.33% and a specificity of 100%. The test exhibited a positive predictive value (PPV) of 100%, whereas the negative predictive value (NPV) was 93.10%. The agreement between the standard SPT and the local SPT was statistically significant, exhibiting moderate concordance (p=0.002). The Indonesian pineapple allergen extract for SPT can serve as an alternative diagnostic tool to assess pineapple allergy and sensitization in AD patients.
