1 · What the graph read from 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.

2 · The registry

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

We present the case of an infant female with refractory epilepsy caused by focal cortical dysplasia in the left deep parietal lobe. Despite trials of multiple anti-seizure medications, seizure frequency remained high, prompting the use of laser interstitial thermal therapy (LITT). The patient underwent 2 LITT procedures at 6 and 12 months of age, achieving seizure freedom following the second procedure. This case highlights the precise trajectory planning and secure laser fixation during both procedures. It demonstrates the potential of LITT as a minimally invasive and effective intervention for medically refractory epilepsy in infants, a population with limited treatment options. The patient's developmental progress following seizure control further highlighted the importance of early intervention in preserving neurological function. This case represents a significant step forward in better understanding LITT for paediatric epilepsy, particularly in infants under 2 years old.
