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
introductionTo determine if there was an association of the ALC (absolute lymphocyte count) and LCP (lymphocytopenia) with the expression of MMP-2 in bone marrow micro-metastasis, the changes occurring during follow-up and association with biochemical failure. METHODS AND PATIENTS: One month after surgery blood and bone marrow samples were taken to determine the presence of micro-metastasis, the presence of circulating prostate cells (CPCs) and ALC. CPCs and micro-metastasis were detected using immunocytochemistry and MMP-2 expression determined in micro-metastasis. Only men positive for micro-metastasis participated in the study. At end follow blood was taken for serum PSA, ALC and CPCs, if the ALC decreased by more than 10% bone marrow sampling was repeated and MMP-2 expression determined, similarly for men with BF. Men who had stable ALCs had an end of study evaluation of the bone marrow.
results402 men underwent radical prostatectomy, one month post surgery 79 men were positive for only bone marrow micro-metastasis and formed the study group; of whom 36/79 (45%) underwent BF. Clinical pathological findings were not significantly different between men with or without BF. In men with BF the ALC was significantly lower one-month post surgery. The 5 and 10 year Kaplan-Meier survival was 100% at 5-years and 65% at 10-years for the whole cohort. Men without BF had stable ALCs. A decrease of >10% in the ALC was associated with increasing MMP-2 expression in the micro-metastasis and surrounding stromal tissue, the appearance of CPCs 6-12 months later and BF.
conclusionsthe immune host-tumour cell interaction in the microenvironment is dynamic and changes with time. A decreasing ALC may be a valuable marker in identifying men with high risk of BF and changes in immune mediated dormancy before the PSA rises.
