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
Castration-resistant prostate cancer (CRPC) remains difficult to treat with conventional chemotherapy. We evaluated a stem cell-based enzyme-prodrug strategy using hTERT-immortalized adipose-derived stem cells engineered to express rabbit carboxylesterase 2 (hTERT-ADSC.CE2) in combination with irinotecan (CPT-11). hTERT-ADSC.CE2 cells were generated via lentiviral transduction and confirmed to overexpress CE2. Their tumor-homing capacity toward PC3 prostate cancer cells was assessed, along with prodrug activation, apoptosis induction, and in vivo tumor suppression in a CRPC mouse model. hTERT-ADSC.CE2 cells demonstrated enhanced migration toward PC3 cells and higher expression of tumor-homing factors than the controls. Under CPT-11, they exhibited a strong "suicide" effect and induced selective killing of PC3 cells, with upregulation of BAX and cleaved caspase-3 and downregulation of BCL-2. By day 14, the combination arm showed significantly lower tumor burden than both the control and irinotecan-alone arms (
