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
objectiveThe aim of this study was to evaluate the effect of distance between dental abutments on the accuracy of one-step and two-step impression techniques with polyvinyl siloxane (PVS) material. MATERIALS AND
methodsFour master models were fabricated with different interabutment distances equal to one, two, three, and four premolar lengths 1-4 (L1, L2, L3, and L4). Seven one-step impressions were taken from each master model using PVS impression material (Group A, n = 7). For two-step impressions, a 1.5 mm polyethylene spacer was used over each master model, and impressions were taken (Group B, n = 7). Scans from the casts were superimposed over the master model scans. Accordingly, differences were measured and compared with statistical tests (Kolmogorov-Smirnoff test, Mann-Whitney test, and Friedman's test) to evaluate the effect of interabutment distance within each impression technique group and also compare the one-step and two-step impression techniques. p value < 0.05 was considered statistically significant.
resultsA statistically significant difference was noted among the different edentulous areas in the one-step impression technique group (Group A, p = 0.010). At edentulous span, a statistically significant difference was recorded (p = 0.047) with two-step impression technique being more accurate compared to the one-step impression technique. Friedman's pairwise analysis in Group A demonstrated a significance between one premolar and four premolar interabutment distance groups (p = 0.006).
conclusionThe accuracy of the one-step impression is significantly affected by the increase in interabutment distance from one premolar to four premolar edentulous.
