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
purposeAssess the global neurosurgeon workforce's awareness of neural tube defect (NTD) prevalence, prevention strategies, and clinical time spent on spina bifida (SB) care.
methodsAn online survey was administered to neurosurgeons worldwide between 2021-2022. Categorical responses were analyzed using descriptive analysis. Adjusted and unadjusted logistic regression analyses were conducted to examine the association between the clinical time spent on SB care and NTD prevalence awareness, controlling for sex, income region, pediatric training, and practice years, estimating odds ratios (ORs) and 95% confidence intervals (CIs).
resultsOverall, 234 neurosurgeons (71% participation rate) responded from 64 countries. Respondents included 166 (77%) non-US residents practicing in non-high-income-country (non-HIC) (49%). Most were male (78%), 31-60 years old (80%), and urban-based (76%). Approximately quarter were unaware of the NTD prevalence at the national (28%) or global (24%) level, or the effectiveness of folic acid fortification (FAF) (27%). About 17% reported NTD rates ≥ 20/10,000 live births in their country. Neurosurgeons most often cited supplementation pills (46%) and flour FAF (36%) as the most common strategies to prevent NTD pregnancies. They were more likely to prefer strategies based on flour FAF (48%) and salt FAF (35%). There was a significant positive association between practicing in non-HIC and spending ≥ 20% of clinical time caring for SB (aOR = 6.42, 95% CI = 2.66-15.46, p < 0.001).
conclusionsThis study highlights the need to improve awareness of NTD prevalence and preventive strategies among the neurosurgical community. There is a significant disparity in time spent on SB care between HIC and non-HIC countries. Neurosurgeons can serve as key advocates for global and local SB prevention efforts, with particular emphasis on FAF.
