The use of a smartphone-assisted ventricle catheter guide for Ommaya reservoir placement-experience of a retrospective bi-center study.
Article in Child's nervous system : ChNS : official journal of the International Society for Pediatric Neurosurgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
backgroundFor intraventricular chemotherapy (IVC) as part of many oncological treatment protocols, Ommaya reservoir is enabling repeated access to the cerebro-spinal fluid (CSF). The correct placement of the catheter in the ventricle is essential for correct application of drugs, which is enabled by sophisticated techniques such as neuronavigation.
objectiveIn a bi-center retrospective study, we reviewed our experience using a smartphone-assisted ventricle catheter guide as simple solution for correct Ommaya reservoir placement.
methodsSixty Ommaya reservoirs have been placed in 60 patients between 2011 and 2017 with the smartphone-assisted ventricular catheter guidance technique. Patient characteristics, preoperative frontal and occipital horn ratio (FOHR), postoperative catheter position, and complications were assessed.
resultsThe majority of our patients (71.6%) have got narrow or slit-like ventricles (FOHR ≤ 0.4). All Ommaya reservoirs were placed successfully. Fifty-eight ventricular catheters (97%) were inserted at the first and 2 (3%) at the second attempt using the same technique. No immediate perioperative complications were observed. All catheters (100%) could be used for IVC. Postoperative imaging was available in 52 patients. Thirty-two (61.5%) of ventricular catheters were rated as grade I, 20 (38.5%) as grade II, and none (0%) as grade III. Four patients (6.7%) showed postoperative complications during a median follow-up of 8.5 months (hydrocephalus, n = 1; infection, n = 1; parenchymal cyst around catheter, n = 1; shunt revision, n = 1).
conclusionsThe smartphone-assisted guide offers decent accuracy of ventricle catheter placement with ease and simplicity for a small surgical intervention. We propose this technique as routine tool for Ommaya reservoir placement independent of lateral ventricular size to decrease the rate of ventricle catheter malposition as reasonable alternative to a neuronavigation system.
