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
Modern treatment of childhood acute lymphoblastic leukemia (ALL) has resulted in a high cure rate; however, it can cause central nervous system toxicity. In the present study, a group of 136 ALL survivors were screened for changes in P300. Therapy was conducted according to a modified New York (NY) protocol (30 patients) and two subsequent revisions of a modified Berlin-Frankfurt-Münster (BFM) protocol (32 and 74 patients). The control group consisted of 58 patients. The survivors had significantly prolonged mean latency of P300 (331.31±28.71 vs. 298.14±38.76 msec, P<0.001) and reaction time (439.51±119.86 vs. 380.11±79.94 msec, P=0.002) compared with in the control group. Abnormalities in the endogenous evoked potentials were observed in 36 patients (26.5%). The mean latency time was significantly longer in the treatment groups compared with in the control group (NY: 329.13±28.07 msec, P=0.001; pBFM: 332.97±23.97 msec, P<0.001; BFM95: 331.47±31.05 msec, P<0.001). The reaction time was equally prolonged in both groups. In comparisons between the studied groups and the control group the most significant prolongation was recorded in the NY group (461.8±140.3 vs. 380.1±78.04 msec, P=0.039). Significantly higher frequency of prolonged reaction time in non-irradiated patients that received BFM95 was also revealed (21.62 vs. 15.85%, P=0.007). In addition, radiotherapy significantly reduced the P300 wave amplitude (mean values: 10.395±5.727 vs. 12.739±6.508 mV, P=0.027). In conclusion, endogenous P300 event-related potentials may be a useful tool in screening of subclinical cognitive changes in ALL survivors.
