1 · What the graph read from it

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.

2 · The registry

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/purpose: Our previous studies found the serum gastric parietal cell antibody (GPCA) positivity in 12.3%-26.7% of atrophic glossitis (AG), burning mouth syndrome (BMS), and oral lichen planus (OLP) patients. This study assessed whether GPCA-positive oral mucosal disease (GPCA Materials and methods: The mean corpuscular volume, blood Hb, and serum iron, vitamin B12, homocysteine, and GPCA levels were measured and compared between any two of three groups of 532 GPCA Results: We found that 532 GPCA Conclusion: GPCA
