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
objectiveTo digitally measure and analyze the anatomical characteristics of protrusive and intercuspal position (ICP) occlusal contacts in maxillary incisors, thereby establishing a standardized measurement protocol and obtaining characteristic functional data to optimize the incisal guidance design of prostheses.
methodsThirty subjects with stable incisal guidance were recruited. Digital dental mo-dels were acquired
resultsAll measured parameters demonstrated good test-retest reliability. No significant differences were found in any parameters between homologous teeth (
conclusionThe anatomical characteristics of protrusive and ICP occlusal contacts in maxillary incisors demonstrated bilateral symmetry. Protrusive movement was primarily guided by the maxillary central incisors, with the guiding area of the central incisors being approximately three times that of the lateral incisors. The marginal ridges and incisal ridges were the main guiding locations. Central and lateral incisors exhibited comparable occlusal contact area in ICP.
