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
Abstract Background/purpose: Oral submucous fibrosis (OSF) is a progressive fibrotic oral mucosal disease associated with betel quid chewing. This study evaluated whether Taiwanese male OSF patients with vitamin B12 deficiency (the serum vitamin B12 level ≤ 450 pg/mL, B12-deficient OSF patients) had high frequencies of blood hemoglobin (Hb) and serum iron and folic acid deficiencies, and serum gastric parietal cell antibody (GPCA) positivity. Materials and methods: The blood Hb and serum iron, vitamin B12, folic acid, and GPCA concentrations in 66 Taiwanese male B12-deficient OSF patients were measured and compared with the corresponding data in 132 age-matched healthy male control subjects. Results: We found that 6 (9.1%), 19 (28.8%), 35 (53.0%), and 9 (13.6%) of the 66 B12-deficient OSF patients had blood Hb (<13 g/dL) and serum iron (≤70 μg/dL), and folic acid (≤6 ng/mL) deficiencies, and serum GPCA positivity, respectively. Furthermore, 66 OSF patients had significantly higher frequencies of blood Hb and serum iron and folic acid deficiencies, and serum GPCA positivity than 132 healthy control subjects (all Conclusion: Taiwanese male B12-deficient OSF patients have high frequencies of blood Hb, serum iron and folic acid deficiencies, and serum GPCA positivity. The anemia and hematinic deficiencies in B12-deficient OSF patients are likely due to OSF symptoms and signs-caused insufficient intake, poor chewing, and malabsorption of hematinic elements from ingested food stuffs rather than the GPCA positivity.
