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 purpose of this study was to investigate the correlation between sperm mitochondrial NADH dehydrogenase subunit 5 (ND5) and NADH dehydrogenase subunit 6 (ND6) gene variations and total fertilisation failure (TFF). MATERIAL AND

methodsA total of 232 sperm samples at the fresh in vitro fertilisation (IVF) cycle or the half-intracytoplasmic sperm injection (ICSI) cycle were collected for this retrospective controlled study on Han Chinese people between July 2011 and April 2014. Of the 232 total samples, 45 were from the IVF-TFF group and 187 were from couples with normal fertilisation (fertilisation rate > 50%). The mitochondrial ND5 and ND6 gene variations and sperm haplotypes were confirmed using nested PCR and DNA sequencing.

resultsTen homozygous variations were newly discovered, namely C12417T, T12441A, C12543A, C13650A, C13765A, T13769C, C13775T, A13776G, C13785A and C13845T. The gene variation rates of six sites, C12417T, C13650A, C13765A, T13769C, C13785A and C13845T, in the TFF group were significantly higher than those in the control group (

conclusionsOur results suggested that the ND5 and ND6 gene variations are correlated with TFF. Furthermore, this study indicated that haplogroup R and haplogroup D4a might be risk factors for TFF.
