Evaluation of collagen sponge and xenografts versus collagen sponge alone in alveolar ridge preservation: a randomized controlled clinical trial.
Trial report in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
This study evaluated the clinical, radiographic, and histological outcomes of alveolar ridge preservation (ARP) using collagen sponge with xenografts (CS + Xenografts) versus collagen sponge (CS) alone, compared to spontaneous healing. 36 extraction sockets were randomly allocated into three groups: Group I (CS + Xenografts), Group II (CS alone), and Group III (control) spontaneous healing. Soft tissue assessment and CBCT imaging were conducted before tooth extraction (baseline) and 6 months post-extraction, followed by histologic and histomorphometric analysis of bone biopsies. Groups I and II exhibited minimal vertical and horizontal soft tissue changes compared to the control group (P < 0.001), with no statistically significant difference between Group I and II (P ≥ 0.05). Vertical and horizontal bone resorption was significantly lower in Groups I and II than in the control group (P < 0.001), with no statistically significant difference between Groups I and II regarding vertical bone loss (P = 0.477 and 0.108, respectively); percent of changes were 8.68 ± 2.69 and 8.61 ± 2.14 respectively. The greatest reduction in alveolar bone width was observed at 1 mm: 17.81 ± 3.97 (Group I), 19 ± 2.77 (Group II), and 41.79 ± 10.3 (Group III); overall P < 0.001. Histologically, Group I had the highest area% of lamellar bone and no residual inflammation, followed by Group II, which showed more inflammation; Group III had the lowest area% of lamellar bone. Intervention techniques were clinically and radiographically proven effective in ARP, however, CS + Xenografts histological results showed more lamellar bone and less residual inflammations.
