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

Poly (ADP-ribose) polymerase (PARP) inhibitors (PARPis) are effective agents in different tumor types. A typical class of adverse events (AEs) associated with these agents, often leading to treatment modifications and discontinuations of treatment, is hematological toxicity. In our systematic review and safety meta-analysis, we investigated the incidence and risk of all grades and ≥ grade (G) 3 hematological AEs, including anemia, neutropenia, thrombocytopenia, and acute myeloid leukemia (AML)/myelodysplastic syndrome (MDS) due to PARPis, used alone or in combination, in patients diagnosed with solid tumors. This systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. We systematically searched the PubMed, EMBASE, and Cochrane databases, the American Society of Clinical Oncology, and the European Society of Medical Oncology meeting abstracts for randomized clinical trials (RCTs) concerning the use of PARPis in patients with solid tumors. The search deadline was April 30, 2024. We calculated risk ratios (RRs) for all-grade and ≥ G3 AEs of PARPis versus non-PARPis. 31 phase II/III RCTs were included. Anemia was the most common all-grade (49.2%) and ≥ G3 AE (25.0%). The administration of PARPis significantly increased the risk of developing all grades of anemia (RR = 2.15, p < 0.00001), neutropenia (RR = 1.50, p = 0.0002), and thrombocytopenia (RR = 2.59, p < 0.00001) compared to non-PARPis. Similarly, a significant increase in the risk of ≥ G3 anemia (RR = 5.43, p < 0.00001), neutropenia (RR = 1.70, p = 0.002), and thrombocytopenia (RR = 5.42, p < 0.00001) was detected. PARPis did not increase the risk of AML/MDS (p = 0.86). PARPis increase the risk of hematologic toxicity compared to other treatments in solid tumors. Clinicians should be aware of this risk, especially given the expected increase in PARPis use in the next year in different tumor types.
