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

Purpose: Vitamin D plays an essential role in subchondral bone, cartilage, and periarticular muscle. This study aims to assess the prevalence of vitamin D deficiency in temporomandibular disorder (TMD) patients. Materials and methods: This is a cross-sectional study. Subjects were assigned into two groups based on having signs and symptoms of TMD: Group 1: subjects had TMD, and group 2 healthy group (control group). The serum level of vitamin D was measured in the two groups. The independent t test was used to compare the serum level of vitamin D between the study and control groups. Results: One hundred ten subjects were studied into two groups (55 subjects in each group). The mean serum level of vitamin D was 18.13 ± 6.38 ng/mL in the study group and 31.83 ± 7.00 ng/mL in the control group. Analysis of the data demonstrated a significant difference in the mean serum level of vitamin D between the study and control groups ( Conclusion: It seems the serum level of vitamin D is lower in TMD patients than in the healthy control group.
