T CD3+CD8+ lymphocytes are more susceptible for apoptosis in the first trimester of normal human pregnancy.

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
aimsNormal human pregnancy is a complex process of many immunoregulatory mechanisms which protect fetus from the activation of the maternal immune system. The aim of the study was to investigate the apoptosis of lymphocytes in peripheral blood of normal pregnant patients and healthy nonpregnant women.
methodsSixty pregnant women and 17 nonpregnant women were included in the study. Lymphocytes were isolated and labeled with anti-CD3, anti-CD4, and anti-CD8 monoclonal antibodies. Apoptosis was detected by CMXRos staining and analyzed using the flow cytometric method.
resultsWe found significantly higher apoptosis of total lymphocytes in peripheral blood of pregnant patients when compared to healthy nonpregnant women. The percentage of apoptotic T CD3(+)CD8(+) cells in the first trimester was significantly higher when compared to the third trimester of normal pregnancy. The ratio of T CD3(+)CD4(+) : T CD3(+)CD8(+) apoptotic lymphocytes was significantly lower in the first trimester when compared to other trimesters of pregnancy and to both of the phases of the menstrual cycle.
conclusionsThe higher apoptosis of T CD3(+)CD8(+) lymphocytes and the lower ratio of T CD3(+)CD4(+) : T CD3(+)CD8(+) apoptotic cells in the first trimester of normal pregnancy may suggest a higher susceptibility of T CD3(+)CD8(+) cells for apoptosis as a protective mechanism at the early stage of pregnancy.
