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
Apoptosis-related proteins and proliferation activity and their relationship with Epstein-Barr Virus (EBV) are contemporary issues in pediatric non-Hodgkin's lymphoma (pNHL). In this study prognostic or pathogenetic role of EBV latent infection, proliferating activity, and apoptosis-regulating proteins in pNHL were explored. EBV-EBER, lmp-1, ki-67, bcl-2, survivin, bax, fas, c-myc, p53 and apoptotic index by TUNEL method were explored in 70 pNHL cases and evaluated statistically. Of the 70 cases evaluated, 24 were female and 46 were male. Seven cases were stage I/II and 63 cases were stage III/IV. The mean age was 7.16 + or - 3.72(1-15). EBV was positive in (25.7%) cases. Overall survival was 82%, while event free survival was 75%. Bax was expressed in 40% of the cases, while the expression of bcl-2,was 50%, survivin 42.9%, p53 8.6%, fas 18.6% and c-myc in 45.7%. Mean apoptotic index was 131.29 + or - 96.69 per 5,000 cells. Mean proliferation index was 55.97% (12-92%). Fas positivity was high in EBV positive cases (p = 0.0001). EBV positivity was not related with prognosis. Apoptotic index was found to be an independent prognostic factor (p = 0.017). Our results suggest that apoptosis-regulating proteins have a role in the pathogenesis of pNHL. EBV was correlated with apoptotic index and fas, bcl-2. No correlation was observed with proliferation index and studied factors. High apoptotic index was related with good prognosis.
