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
purposeThis study evaluated a modified anchoring technique using a straight connector in non-burr hole valve shunt systems to reduce catheter migration in children under 3 years of age.
methodsWe retrospectively reviewed records of 48 children (< 3 years) who received frontal ventriculoperitoneal (VP) shunt placement using a non-burr hole valve system between January 2017 and July 2022.
resultsCatheter migration occurred in 18 of 48 patients. Migration was significantly higher with the right-angle adaptor (61.5%) than with the straight connector (9.1%; p = 0.0002). Younger age at surgery was associated with migration (4.5 vs. 10.1 months, p = 0.0048). Univariate analysis showed younger age and use of the straight connector were associated with reduced migration risk.
conclusionsIn this small retrospective study, anchoring the straight connector was associated with fewer catheter migration events, but the difference was not statistically significant after adjustment for age. These findings should be interpreted as exploratory, highlighting a potential technical consideration rather than a proven benefit. Further prospective studies with larger and age-stratified cohorts are needed to determine whether this modification contributes meaningfully to reducing shunt migration.
