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

objectiveThis study was performed to evaluate the trabecular pattern of patients with cancer taking bisphosphonates on panoramic images using fractal dimension (FD) analysis by comparison with healthy subjects and to assess whether any difference exists between regions.

methodsFD analysis was conducted using ImageJ 1.3 software (National Institutes of Health, Bethesda, MD, USA) with the box-counting method on panoramic radiographs of 33 patients taking bisphosphonates (13 males and 20 females) and 33 healthy sex- and age-matched individuals.

resultsFD values were higher (1.39 ± 0.14) in the study group than control group (1.38 ± 0.07) (p ≤ 0.05). No difference was detected in the FD values among the tested regions. The mean FD values in the control and study groups were as follows: region 1, 1.49 and 1.41 (p = 0.54); region 2, 1.36 and 1.37 (p = 0.84); region 3, 1.35 and 1.42 (p = 0.11); and region 4, 1.39 and 1.39 (p = 0.90), respectively. Female patients showed significantly lower values above the mandibular canal on the distal side of the second premolar and anterior to the mental foramen than did male patients (p ≤ 0.05). Age was unrelated to the FD in the study group (p ≥ 0.05).

conclusionsThe FD values of the patients with cancer taking bisphosphonates were higher than those of the controls. FD analysis showed the potential for examining bone structure in panoramic radiographs. Studies with a larger sample size are necessary to confirm these results.
