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

objectiveTo evaluate the effectiveness of intracytoplasmic sperm injection (ICSI) in improving fertilization rates compared to conventional in vitro fertilization rates (IVF) among women aged ≥38 years with a non-male factor diagnosis.

designSystematic review and meta-analysis.

settingNot applicable. PATIENT(S): Women aged ≥38 years with a non-male factor diagnosis receiving IVF or ICSI. INTERVENTION(S): A systematic review of databases including PubMed and Embase was performed. Study protocol was registered at the International Prospective Register of Systematic Reviews. Studies were selected if they compared fertilization rates from ICSI with those from conventional IVF among women aged ≥38 years with a non-male factor infertility diagnosis. A random effects model was used. Meta-analysis of Observational Studies in Epidemiology guidelines were applied. MAIN OUTCOME MEASURE(S): Fertilization rate.

resultsSeven studies including 8796 retrieved oocytes (ICSI: 4,369; IVF: 4,427) with mean female age ≥38 years met the inclusion criteria. There was no significant difference in fertilization rates between ICSI and conventional IVF (relative risk [RR] 0.99, 95% confidence interval [CI] 0.93-1.06; P = .8). Heterogeneity was observed between studies (I

conclusionsNo difference was found in fertilization rates between conventional IVF and ICSI. Further studies are needed to assess the impact of ICSI in this population, controlling for other indications such as preimplantation genetic testing.
