1. 01۱۹۸۹First Post-War Five-Year Plan (Rafsanjani reconstruction)قوت ارتباط

   Rafsanjani government begins post-war economic liberalization and reconstruction planning after Khomeini's death (June 1989).

   چرایی این پیوند: Maternal deaths fell from 2,200 (1989) to 1,300 (1993) to 460 (2000) to a series-low 240 (2019) -- one of the most dramatic sustained maternal-health improvements in this database -- driven by the post-war expansion of the rural Primary Health Care network (Behvarz health houses) and the same national family-planning program that collapsed Iran's fertility rate over this period (see the companion fertility-rate chart), extending contraceptive access, antenatal care and skilled birth attendance into previously underserved rural areas.

   ملاحظه: WDI/UN inter-agency MMR estimates are themselves modeled, not raw vital-registration counts, especially for the earlier years; the estimation methodology was revised more than once over this 40-year span, so part of the smoothness of the decline may reflect improved modeling as much as a literal count of prevented deaths.

2. 02۲۰۲۰COVID-19 declared a pandemicقوت ارتباط

   WHO declaration triggers synchronized global lockdowns, an oil-demand collapse (WTI briefly trades negative on 20 April 2020), and unprecedented fiscal/monetary stimulus across every country in this database.

   چرایی این پیوند: After reaching a series-low of 240 (2019), reported maternal deaths rose to 420 (2020) and 610 (2021) before falling back to 250 (2022) and a new low of 190 (2023) -- consistent with pandemic-era disruption to antenatal-care access and hospital capacity documented globally, with a rapid reversion once the disruption passed. The chart's own companion 'lifetime risk of maternal death' metric shows the same temporary reversal (1 in 3,135 in 2019 to 1 in 1,243 in 2021).

   ملاحظه: A two-year, roughly 2.5x reversal in an otherwise steadily improving series is unusual enough to be read as a real signal rather than noise, but no Iran-specific clinical study is cited here confirming the precise mechanism (reduced antenatal visits vs. COVID-19 infection in pregnancy vs. reporting artifacts).
