Optic nerve sheath diameter as a prognostic tool for postdural puncture headache in pregnant women undergoing caesarean section under spinal anesthesia: A cross-sectional study.

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
Context: Postdural puncture headache (PDPH) is a common and debilitating complication following spinal anesthesia in obstetric patients, with few objective tools available for early prediction. Optic nerve sheath diameter (ONSD) measured by ultrasonography is a noninvasive surrogate marker of intracranial pressure changes and may aid in early risk stratification. Aim: To evaluate the prognostic utility of ONSD measurements in predicting PDPH among pregnant women undergoing cesarean section under spinal anesthesia. Materials and Methods: This cross-sectional study included 88 pregnant women aged between 18 and 40 years undergoing cesarean section under spinal anesthesia. ONSD was measured using ultrasonography with a 13-6 MHz probe at baseline (T0) and at 4 (T4), 24 (T24), 48 (T48), and 72 h (T72) postprocedure. PDPH was diagnosed using International Classification of Headache Disorders criteria. Statistical Analysis Used: Data were analyzed using SPSS version 22. Continuous variables were expressed as mean ± SD and categorical variables as frequencies and percentages. Student's Results: PDPH occurred in 12 patients (13.6%). Baseline ONSD values were comparable between groups. Patients who developed PDPH showed significantly lower ONSD values from T4 onward ( Conclusion: ONSD measurement at 72 h postspinal anesthesia is a sensitive and clinically useful prognostic tool for predicting PDPH in obstetric patients and may be incorporated into routine postoperative monitoring.
