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
objectiveThis study aimed to evaluate the turnaround time (TAT) of histopathology reports for pediatric small round blue cell tumors (PSRBCTs) at the largest pediatric tertiary care center in the Philippines, and to identify the factors affecting TAT. Additionally, the reasons for the inability to accurately diagnose cases were investigated.
methodsA retrospective cross-sectional study was conducted on 232 tumor cases from 2018 to 2022. The overall mean TAT, as well as the TAT for specific phases (pre-analytical, analytical, and post-analytical), was determined. Factors contributing to delays in diagnosis were analyzed. Multivariate analysis was used to assess associations between these factors, and Spearman correlation was applied to explore the relationship between the number of consultant pathologists who reviewed a case and the mean TAT.
resultThe overall mean TAT for PSRBCT histopathology reports was 13.39 days. The pre-analytical, analytical, and post-analytical phases had TATs of 1.89, 11.56, and 4.53 days, respectively. Unavailability of immunohistochemical stains significantly increased TAT (95% CI, p-value < 0.01). A significant reduction in TAT was observed during the COVID-19 pandemic (95% CI, p-value < 0.01). A direct correlation was found between the number of consultant pathologists reviewing a case and the mean TAT (95% CI, p-value < 0.01). The main barrier to rendering a specific diagnosis was the lack of access to molecular tests.
conclusionProlonged TAT reflects underlying issues that delay the accurate diagnosis of PSRBCTs. The identified deficiencies, including limited access to ancillary tests and specialized expertise, offer opportunities to improve pediatric cancer care in the Philippines.
