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
Background: Postdural puncture headache (PDPH) is a significant complication of spinal anaesthesia, especially in obstetric patients. It is triggered by the leakage of cerebrospinal fluid (CSF) through the puncture in the Dura mater. Understanding the timing of PDPH onset is crucial for early diagnosis and treatment, but previous studies have not fully explored its timing and associated factors. Aim: To determine the incidence and predictors of PDPH in women who deliver by caesarean section under spinal anaesthesia. Methods: A prospective follow-up study was conducted from March 7 to May 8, 2025, among 365 mothers who underwent caesarean section under spinal anaesthesia at government hospitals found in Debre Berhan, Ethiopia. Data were collected using a structured interviewer-administered questionnaire. The Kaplan-Meier method was used to estimate the survival time for PDPH, with the log-rank test for curve comparison. Cox regression analysis was conducted to identify predictor variables. Results: The cumulative incidence of PDPH was 33.7% (95% CI: 28.9%, 38.7%), and incidence density was 3.75 (95% CI: 3.11, 4.47) per 1000 person-hours of observation. The mean time to onset of PDPH was 28.9 h (approximately 1.4 days). The restricted mean survival time was 28.98 Hr (95% CI: 25.78, 32.17). Multiple attempts during the procedure AHR 1.69 (95% CI: 1.104, 2.606; Conclusion: This study confirmed that reducing the magnitude of PDPH requires limiting the number of puncture attempts and usage of Quincke spinal needles (22G) or fine-gauge needles (24G-26G).
