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
backgroundPost-lumbar puncture headache (PLPH) is the most frequent complication of diagnostic lumbar puncture (LP). Data from academic outpatient neurology settings are limited, although these environments are increasingly relevant for both clinical care and resident training.
methodsWe retrospectively analyzed consecutive cases of diagnostic LP. Procedures were performed by first-year neurology residents under supervision, using 22-gauge cutting bevel needles, in an academic outpatient setting. The primary outcome was PLPH incidence; secondary outcomes included other complications. Exploratory univariate logistic regression was performed to identify predictors of PLPH.
resultsA total of 177 patients (mean age 58.0 ± 16.5 years; 52% female) were included. PLPH occurred in 11 patients (6.2%), with a mean onset of 36.7 ± 25.7 hours and mean duration of 3.7 ± 1.9 days. Younger age and a higher number of puncture attempts were significantly associated with PLPH. Other variables, including gender, BMI, CSF volume collected, and patient position, were not significantly associated. Other complications were rare and self-limiting.
conclusionsIn this real-world academic outpatient setting, PLPH incidence was 6.2%. Younger age represented a non-modifiable predictor, whereas multiple puncture attempts emerged as a potentially modifiable factor. These findings underscore the importance of procedural planning and structured supervision, and support the implementation of simulation-based educational strategies to reduce complication rates among trainees.
