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

purposeTo investigate 24 h in vitro maturation (IVM) of cumulus-stripped immature oocytes from stimulated cycles.

methods263 oocytes identified as immature after cumulus stripping for ICSI were subjected to in vitro maturation (IVM). Fertilization rates and reproductive outcomes of matured oocytes were compared against 234 in vivo matured sibling oocytes (IVO-MII-Sib) from the same cycles (n = 41). Day 2 embryo development was compared against 116 embryos from ICSI cycles having no IVM (IVO-Ext controls).

resultsWhile fertilization rates were similar between IVM and IVO-MII-Sib oocytes (62.1% vs. 64.0%, p = 0.9909), day 2 embryo quality was reduced in the IVM group compared with IVO-Ext controls as evidenced by fewer embryos having 4 cells (28.3% vs. 54.3%, p = 0.0026), low fragmentation (30.0% vs. 65.2%, p < 0.0001) or perfectly symmetric blastomeres (28.6% vs. 46.9%, p = 0.0371). 0 of 17 IVM embryos with known fate implanted.

conclusionEfficacy of 24 h IVM for cumulus-stripped GV and MI oocytes for either clinical use or study of normal meiotic maturation is questionable.
