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

BACKGROUND AND

methodsSurgery remains the standard of care for non-small cell lung cancer (NSCLC) but is applicable to ≤ 30% of patients. Pulsed Electric Fields (PEF) ablation uses short-duration, high-voltage electrical pulses to induce cell death without relying on thermal mechanisms. Safety findings are reported from a two-arm, non-randomized, study evaluating the use of PEF in patients with early-stage NSCLC.

methodsPEF energy was delivered bronchoscopically or percutaneously to 36 patients with suspected or confirmed early-stage NSCLC approximately 20 days before resection; 8 control patients had biopsy only. The primary safety analysis was the device and/or procedure related serious adverse events (AEs) rate from PEF procedure through resection. Immunohistochemical evaluation of resected tissue was also assessed.

resultsPEF was delivered to all patients in the treatment group after biopsy of targeted tumor. No device or procedure-related AE were observed. Histopathological assessment of resected tumors demonstrated a cellular depletion zone characterized by decrease or absence of tumor cellularity and a variable degree of inflammation. Tertiary lymphoid structures were observed within PEF-treated tumors.

conclusionsThese clinical observations and histopathologic tissue alterations, indicate that PEF energy delivery is feasible and safe in NSCLC, with potential signals of immune system activation.
