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 retrospective study analyzed crown fractures in the permanent dentition among pediatric patients attending the Pediatric Dentistry Department, Medical University of Warsaw, during the COVID-19 lockdown. Data from 1582 medical records were reviewed, and 56 patients (mean age 9.4 years, SD 25.3) with 74 crown fracture cases were included. Traumatic dental injuries (TDIs) accounted for 14.7% (233/1582) of cases, with crown fractures constituting 42.9% (100/233). The mean time interval before patient presentation was 0.4 days (SD 0.63). Falls (51.8%) were the most common cause of injury, with most incidents occurring at home (32.1%). The maxillary central incisors were most frequently affected (86.0%), and concomitant soft tissue injuries were observed in 33.9% of cases. Complicated crown fractures (CCFs) were most often treated with Root Canal Treatment (RCT) (37.5%) and had a lower success rate compared to uncomplicated crown fractures (UCFs) (37.5% vs. 70.7%; p < 0.05). Composite restorations achieved the highest success rate (70.0%) compared to reattachment (33.3%) and glass-ionomer cement (16.7%) (p < 0.05). A significant difference in the time interval between dental injury and dental examination was observed between successful and unsuccessful cases (p < 0.05). The most common complication was loss of pulp vitality, occurring in 27.3% of CCFs and 70.5% of UCFs (p < 0.05). The findings highlight the impact of the COVID-19 pandemic on TDIs, including the increased occurrence of injuries at home and the challenges of timely access to dental care. These results underscore the importance of prompt and appropriate management to improve treatment outcomes during unprecedented circumstances like the pandemic. The study underlines the importance of maintaining dental emergencies in order to facilitate support mechanisms for patients, management strategies for dental professionals, and appropriate allocation of resources. Dental management of crown fractures should follow recent clinical guidelines. Awareness and knowledge concerning dental injuries are insufficient and should be improved.
