1 · What the graph read from it

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.

2 · The registry

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

introductionThe pro- and anti-inflammatory cytokines play crucial role in the development and functions of placenta. Any changes in these cytokines may be associated with many pregnancy-related disorders like preeclampsia. Therefore, the present study is aimed to study the expression of pro-inflammatory (TNF-α, IL-6) and anti-inflammatory (IL-4, IL-10) cytokines in placenta and serum of preeclamptic pregnant women. MATERIAL AND

methodsFor this study, a total of 194 cases of preeclamptic and control cases were enrolled in two Groups as per the gestational age that is, Group I (28-36 weeks) and II (37 weeks onwards). The number of samples was 55 in Group I and 139 in Group II. The immunohistochemistry (IHC) and enzyme-linked immunosorbent assay (ELISA) were conducted on placenta and serum of both preeclamptic and normal samples, respectively. IHC results were revalidated by reverse transcriptase PCR (RT-PCR).

resultsBoth Groups (I, II) of preeclampsia showed amended levels of pro- and anti-inflammatory cytokines in placental tissues and serum samples. The levels of TNF-α and IL-6 were significantly increased in preeclamptic cases (P = 0.0001, P = 0.0001) while the IL-4 and IL-10 were downregulated (P = 0.0001, P = 0.0001) in comparison to control. In addition, a negative correlation was also observed between the two in preeclampsia (P = 0.0001).

conclusionThe balanced ratio of pro- and anti-inflammatory cytokines is essential to regulate the maternal inflammation system throughout pregnancy. Therefore, the gradual cytokine profiling of the pregnant women may be useful for the management of preeclampsia.
