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
aimThe aim of the study was to investigate the correlation between index finger length and occlusal vertical dimension (OVD) across different facial morphological types in dentate adults of West Bengal population. SETTINGS AND
designA cross-sectional observational study was conducted among 212 dentate adults (122 males and 90 females) aged 25-55 years attending the outpatient department of Dr R Ahmed Dental College and Hospital, Kolkata, West Bengal, India. MATERIALS AND
methodsParticipants were classified into three facial types based on facial index: euryprosopic ( n = 86), mesoprosopic ( n = 66), and leptoprosopic ( n = 60). Index finger length was measured from the fingertip to the metacarpophalangeal joint using a digital caliper. OVD was measured from subnasale to gnathion using the Willis gauge. STATISTICAL ANALYSIS USED: Shapiro-Wilk test for normality, Pearson/Spearman correlation coefficients, analysis of variance/Kruskal-Wallis tests for group comparisons, and multiple linear regression modeling were used. Statistical significance was set at P < 0.05.
resultsSignificant positive correlations were found between index finger length and OVD across all facial types (Mesoprosopic: ρ = 0.555, P < 0.001; Euryprosopic: r = 0.505, P < 0.001; and Leptoprosopic: r = 0.459, P < 0.001). The overall correlation coefficient was 0.503 ( P < 0.001). Multiple regression analysis revealed that index finger length significantly predicted OVD (β = 0.424, P < 0.001), with the model explaining 26.7% of variance ( R² = 0.267, F = 18.90, P < 0.001). The predictive equation was: OVD = 4.03 + 0.41 × finger length.
conclusionIndex finger length demonstrates a moderate positive correlation with OVD across all facial types, suggesting its potential as a supplementary anthropometric guide for OVD estimation in clinical practice.
