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

backgroundWedge-shaped defects are rarely reported in single mandibular denture (SMD). This report describes an unusual unilateral wedge-shaped defect observed in an SMD and discusses its possible etiological factors. CASE PRESENTATION: A 58-year-old woman presented with sensitivity in the left maxillary posterior teeth. Clinical examination revealed wedge-shaped defects in the left maxillary molars and a unilateral wedge-shaped defect approximately 3 mm in depth on the left side of the mandibular denture base. The patient denied bruxism or traumatic injury to the prosthesis but reported a long-standing habit of unilateral mastication.

conclusionThis case suggests that long-term unilateral mastication may be associated with the development of localized wedge-shaped defects in SMDs. Comprehensive occlusal assessment and regular prosthesis maintenance may help prevent similar complications.
