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.

Abstract

objectiveTo evaluate whether platelet-rich plasma (PRP) optimizes endometrial thickness (EMT) and improves live birth rates (LBR) in women with refractory thin endometrium due to varied aetiology during fresh in vitro fertilization (IVF) and frozen-thawed embryo transfer (FET).

methodsA prospective interventional study was conducted at the ART Centre of a tertiary care academic hospital. Twenty-two infertile women with refractory thin endometrium (<7mm) despite standard hormone replacement therapy were assessed. Twenty patients underwent 26 PRP cycles from December 2018 - June 2020 during fresh IVF-ET and FET. Primary endpoint was expansion of EMT and secondary outcomes were implantation rate (IR), clinical pregnancy rate (CPR) and LBR in fresh and FET cycles and aetiology wise.

resultsMean EMT increased significantly following PRP administration (p<0.001) with average increase of 1.07mm and 0.83mm after first PRP (p<0.001) during fresh IVF and FET, respectively. CPR, IR and LBR showed no significant difference when compared during fresh vs. FET cycles (p>0.05). PRP led to significant increase in EMT in tuberculosis (TB), diminished ovarian reserve (DOR) and polycystic ovary syndrome (PCOS) (p<0.001). There was no significant difference in CPR, IR and LBR among three aetiological factors (p>0.05). Overall, clinical pregnancy and LBR reached up to 20% and 25%, respectively. No adverse reactions were reported.

conclusionsPRP enhances EMT significantly during fresh and FET cycles in thin endometrium associated with TB, PCOS and DOR, thus improving the CPR and LBR in these low prognosis patients.
