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: Bullous pemphigoid (BP) is characterized by tissue-bound and circulating Immunoglobulin G (IgG) autoantibodies against BP 180 and BP 230. Diagnosis of BP is a multi-step procedure. Enzyme-linked immunosorbent assay (ELISA) is a quantitative analysis of target antigens, whereas BIOCHIP mosaic-based indirect immunofluorescence (IIF) has a combination of screening and target antigen-specific substrates in a single miniature incubation field. This study is done to compare BIOCHIP mosaic based IIF and ELISA for the diagnosis of BP. Materials and Methods: A total of 42 biopsy and/or direct immunofluorescence (DIF) proven BP patients were included in the study. Serum was subjected to BIOCHIP mosaic-based IIF and ELISA. The results were then compared. Results: Using ELISA, the sensitivity of BP 180 and BP 230 was 92.3% and 54.5%, respectively. The sensitivity of BP 180 and BP 230 by BIOCHIP was 77.4% and 60%, respectively. The association between ELISA and BIOCHIP was analyzed using the Chi-square test and was found to be statistically significant with a Conclusion: Our study concluded that both BIOCHIP and ELISA showed comparable sensitivity in diagnosing BP. Both are non-invasive, less time-consuming, and provide fast results. However, BIOCHIP can delineate bullous pemphigoid from other sub-epidermal bullous diseases.
